Yes, this is a full synthesis of the p43 snark loop. At times this synthesis lurches forward like a slow salvo construction, and indeed I tried using slmake a few times to prise off the central still lifes, but in the end manual placement of gliders and a whole lot of three-glidering and rummaging through Niemiec's files won out. The final cost is 226 gliders; if you have any improvements, please let me know here.

A similar strategy should be available to synthesise any larger snark loop. With these and a few other oscillators I've already added to Shinjuku, for every period with a known oscillator there is a synthesis of at least one oscillator of that period, except period 39. The first person to synthesise a non-trivial period-39 oscillator will win a prize from me.

If I remember correctly, the next record-holding snark loop would be p49, right?

[Freywa]

The p49 loop using p7 bumpers is smaller. The next snark-based record is at p53.

Shinjuku already knows how to make Beluchenko's p13, and the block placements are trivial.

Speaking of other periods, it is trivial to take out four gliders to get a p86 loop. The boats in the core aren't needed for this, so the eaters can be made directly and the cost drops to 142 gliders:

[Entity Valkyrie 2]

You forgot to remove the eaters and make it a gun.

[Ian07]

You forgot to remove the eaters and make it a gun.

This is trivial to do just by removing gliders. Do note though that, at least for Shinjuku, it has to be fully capped because Shinjuku doesn't really support linear growth patterns.

[Entity Valkyrie 2]

What is Shinjuku?

[Ian07]

What is Shinjuku?

Oh yeah, I forgot you weren't here when Shinjuku came out in April. Basically it's a new glider synthesis database that runs on lifelib and is used by Catagolue to display syntheses on object pages. You can find more information in this thread. There's also a page on Catagolue where you can browse syntheses and even submit your own now (with a few caveats) and the database on Catagolue updates automatically.

[Entity Valkyrie 2]

A similar strategy should be available to synthesise any larger snark loop. With these and a few other oscillators I've already added to Shinjuku, for every period with a known oscillator there is a synthesis of at least one oscillator of that period, except period 39. The first person to synthesise a non-trivial period-39 oscillator will win a prize from me.

EDIT: Can someone do a demonstration of how to use reverse caber tosser to construct something needing more than 35 gliders (like the p39 oscillator above) with 35 gliders?

EDIT: Can someone do a demonstration of how to use reverse caber tosser to construct something needing more than 35 gliders (like the p39 oscillator above) with 35 gliders?

The Reverse Caber Tosser 35G synthesis of any synthesisable pattern is a theoretical construct. The construction of the pattern is the essence of a proof that such a synthesis is possible. But with current technology and knowledge it is infeasible to construct such a pattern. I don't believe it is currently even possible to calculate the position of all gliders required to construct a pulsar, or other simple object. And it is almost certainly impossible to run such a pattern with any current simulator even if it could be constructed. There has been discussion of this topic in various places on the forum, in particular the original Building a reverse-caber-tosser thread. Dvgrn's post on this specific question is a little more optimistic than my statements here, but I'm unconvinced that we'll see such a pattern running to completion any time soon.

Dvgrn's post on this specific question is a little more optimistic than my statements here, but I'm unconvinced that we'll see such a pattern running to completion any time soon.

There's a more recent post listing all the remaining unsolved issues. It shares pretty much the same view of the RCT as the other post, but might seem a little less optimistic about the possibility of someday running a 35-glider RCT pattern to completion.

Please Can We Just Use A Few More Gliders?
I'd say the biggest problem is that optimizing the RCT all the way down to 35 gliders has made things a lot more difficult. For example, if we had a 99-glider budget instead of a 35-glider budget, we could drop a few blocks here and there to stop all the incoming GPSEs relatively cleanly. In the 35-glider model we have to build those blocks at a ridiculously high cost, with slow^3 gliders.

Just getting those simple "stopper" objects built, before the GPSEs arrive near the construction site, already moves the problem far enough out on the tedious-annoyance scale that no one really wants to spend the time to build a sample -- even though that part is all known technology, and not even all that difficult.

But it gets much more tedious and annoying than that. There's some interesting engineering that could be done, to build a 1G seed constellation for the fleets of Corderships that will clean up the GPSE debris. A sample Cordership fleet has been done for the isolated GPSE in the 59-glider version of the RCT -- it came out to a glider plus 11 Corderships. But then we'd need an even larger seed constellation, waiting behind the first one and activated by the return glider, to produce the meteor shower that cleans up the huge amount of ash left by those eleven Corderships crashing into the GPSE's startup debris.

The Next Few Steps Aren't Too Hard
In the 35-glider model, we'll need completely different cleanup Cordership-fleet seeds for the 3-GPSE group and the 2-GPSE group plus the Sakapuffer -- see the first link above. So if anyone wants to make progress on this project, the first step might be to invent those Cordership cleanup fleets. If someone builds those fleets, I might not be able to resist making actual seed constellations for them.

Here again, we're still definitely within known technology. A set of huge ugly meteor shower seeds for the leftovers from the 3-GPSE and 2-GPSE groups could be compiled by a script fairly easily, and then we really would have explicitly constructed patterns that would show exactly how the large majority of the RCT's temporary debris will be cleaned up. (Let's not get into the BLSE cleanup problem until -- it's even worse, but there's still some hope that it can be avoided... while maybe getting a number even lower than 35!)

... But The Total Project Is Still A Little Bit Crazy
Unfortunately the slow^3-salvo recipes for all of these enormous cleanup seed constellations will have to be coded into the position of the Sakapuffer, along with the recipe for whatever we actually want to build. It just doesn't look good for ever constructing a working Hashlife-runnable pattern. But quite possibly some future HashHashLife algorithm -- or a completely custom RCT-simulation algo -- will be able to do better.

If we allowed ourselves let's say a 999-glider budget instead of just 35 gliders, almost all of these problems would go away: we could construct clean non-GPSE glider sources, and shoot them down cleanly when they weren't needed any more. And shoot down the BLSE instead of stopping it from behind -- or just build a simple block-keeper including self-destruct circuitry, and avoid that whole awkward cleanup problem entirely, too.

Fine, but can you at least demonstrate the 329-glider RCT model for a pulsar?

[dvgrn]

Fine, but can you at least demonstrate the 329-glider RCT model for a pulsar?

Sure, if someone else will do all the time-consuming boring part... except I'd suggest allowing 999 gliders to simplify the cleanup problem, as described above, so we can actually concentrate on using the tape recipe to build the pulsar.

For example, we could just go ahead and pre-construct the block-keeper that calcyman talks about as an intermediate stage of the 35-glider RCT, to increase the efficiency of the recipe and reduce the cleanup problem. Someone could easily figure out the right sequence of bits to build a pulsar instead of a honeyfarm here:

We might have a budget of about 2^12 to 2^16 bits that we can encode into the position of a Cordership and actually run in Golly, before the current HashLife algorithm starts finding the pattern too difficult to handle. So we could build something a bit more impressive than a pulsar if we wanted to, maybe something about as complicated as a Cordership or loafer or Snark -- a rough estimate says any of those might be 4-5K bits with this system.

The Pointless Boring Part
After the object gets constructed is where the tedium sets in. We'll want to use the rest of the 999-glider budget to stop all of the guns and shoot them all down, along with the block-keeper and the remains of the Cordership.

Those are all just gliders that start far far away, like three-plus times as far away as the Cordership, so they'll arrive to do the cleanup safely after the Cordership's signal-bouncing work is done. It wouldn't be difficult to find locations for all those gliders and drop them into the above pattern, but LifeViewer wouldn't like it much (unless they were done with the snazzy new PASTE feature) and I'm not sure what the point would be exactly.

Replacing all of those cleanup gliders with a seed constellation that builds them (or equivalents) would bring the total cost back down closer to 329 gliders, but would also mean that the seed constellation would have to be built along with the pulsar-or-whatever, using bits coming in from the Cordership. That seed constellation isn't too terribly hard to design, but as far as I can see it will cost many orders of magnitude more than 2^16 bits to build, so that's where it becomes impractical to build a demonstration pattern.

Notes So No One Complains About These Particular Things
1) There's a preblock in the southeast part of the pattern, which I lazily put there so I wouldn't have to move the Cordership recipe to switch the bit for the first signal coming back from the Cordership. That's just a little easy math, but it was faster not to do it.
2) The sample honeyfarm recipe is still shown near the block-keeper, and then the bits coming back from the Cordership extend it a bit, to make an equally boring two-beehive recipe.
3) Obviously part of the 999-glider budget would also include building the block-keeper out of gliders. I didn't bother with that because ...
4) ... the block-keeper can be made much more cheaply with a Spartan Hersrch connection between the Herschel receiver and the H-to-block. I just used syringes because they're easier.
5) There are a couple of diametrically opposed gliders fairly far off to the NE and SW, that build a block. That block is another of the objects that is really supposed to be built by the "RCT bits" encoded in the Cordership position, to get the cost down to 329 gliders.

I had earmarked the p49 bumper loop – or at least a larger variant of it – for synthesis soon after completing the p43 loop. Here is a p77 bumper loop in 99 gliders:

P.S. the P49 bumper loop uses 37P7.1, not 38P7.2,

[Freywa]

P.S. the P49 bumper loop uses 37P7.1, not 38P7.2,

I don't care. It's still a p49 bumper loop. Don't be overly picky on details.

[Entity Valkyrie 2]

I thought you are trying to construct the minimal form

[Freywa]

I thought you are trying to construct the minimal form

I'm not. 38P7.2 is much easier to synthesise than 37P7.1, so I chose that. For the purposes of Shinjuku only the period matters.
