I found this final step for 128P10.2 but being a synthesis novice I could not synthesize the constellation (the problem is the eater-on-eaters, I couldn't find a way to synthesize them with the core blocks in place):

Nice! This is a substantial reduction from the previus 20. The pond+2-glider spark can be replaced by 3 gliders, and the tub can be replaced by a 2-glider spark, reducing this to 11. I have 55 other syntheses for larger trivial variants based on this, most of which previously cost >= 1 glider/bit, and this substantially reduces all but one of them (unless a way can be found to tie a boat, that is unobtrusive on both sides).

Wow, how did you find that recipe? I wonder does it have other applications.
It's a pity that it can't be used to complete this baker's dozen variant synthesis if the loaf is placed:

Well, I was browsing through catagolue syntheses and I noticed that more than half of the Buckingham's p64 recipe was taken by a costly eater2 insertion (29G!) and thought that there had to be a way to improve that (especially since the insertion wasn't even that edgy, so I just did some soup-grinding until I found a suitable edgy reaction. (I think you noticed, but the recipe is just pi + teardrop + boat):

Yes.

Getting back on topic, is there a way to perturb the upper left junk around generation 58 or so of this to create an eater in the right spot for a dinner table synthesis (and is there some kind of program that can search for this kind of thing)?

Oops! I know that I created both of these long ago, from the first iteration of my web site. The second one has a time stamp of 1997-04-20; the first was updated more recently, but most of the files in this series have time stamps from that day. I'll have to take a look at this. Thanks for bringing it to my attention.

Here are the eleven six-glider versions that I found: ...
These are great! They save 5 gliders over the previous 11-glider converters. So far, I've found 67 syntheses that this improves, 6 that it does not, and 1 that it improves half of (i.e. there are two Silver's P5s on the same side, and either one can be added the new way, but after that, the other one cannot) (see below). I have 98 more to examine; of these, it looks like there are 10 that it will work for half of.

I created a 24-glider synthesis of the first one on 2019-11-15. Sadly, the new 6-glider converters don't work. For the second one, I haven't been able to simultaneously insert the Z while adding the two Silver's P5s in this (trans+trans) version, nor the other two (cis+trans and cis+cis) versions obtained by flipping the orientation of or both of the Silver's P5s.

Should be easily transformable into the canonical version.
EDIT: Turns out Catagolue didn't accept it. Fixed the synthesis and it should work now.

It looks like you should be able to save two more gliders by using a 90° kickback reaction instead of using two gliders each making two turners, although it haven't tried it, so maybe there's not enough time to construct the blinkers.
Marine has a non-centered Moore neighborhood and at least one elementary gun with a very high period (11,843).

Yup, that certainly works. There's all kinds of room for a 90-degree kickback -- see the circled pairs of gliders below:

There also turned out to be slightly cheaper ways to do setup and cleanup, so this is 32 gliders in all. Some more improvements might be possible. I feel like there's some tricky way to save a glider on the two 3G pi constructions, but wasn't able to figure anything out there.

Yeah, the synthesis was kind of rushed so I didn't bother optimizing. Any table on table to hat converters to transform it to the canonical version?

Has nobody completed the 128P10.2 synthesis I posted at the top of the page?

EDIT: The synthesis has the halves constructed separately, so the monomer can be constructed:

About the other synthesis on that post, do you really need four gliders in the top left just to make a single spark? I'm thinking that that can be more efficient.

You indeed do not need 4 gliders. The current synthesis uses one, plus some trickery:

Code: Select all

#C [[ GRID MAXGRIDSIZE 14 THEME Catagolue ]]
#CSYNTH xp4_xo8wc871zggke33z1 costs 9 gliders (true).

Do you know about Mark Niemiec's glider construction database? You can look up aircraft carriers there, for example -- just paste in the RLE for an AC into the input box, then click on the second "Carrier; Aircraft carrier" link (not the first one!). You'll get ideas about building two of those pseudo-AC pairs with the reaction below left, and maybe a couple more individual ACs with the reaction below right.

But the last two ACs are definitely getting tricky, and I'm far beyond my own beginner-level expertise here. Maybe there's a one-time-turner way of getting the conflicting gliders past the already-built pseudo-AC pairs, to use the below-left recipe on all four sides?

My database also includes pseudo-still-lifes. In this particular case, you could build the first pair of carriers from just six gliders. The next two could be built by injecting a carrier (4) and adding an inducting one (7). The final pair would be a bit more of a challenge.

But the last two ACs are definitely getting tricky, and I'm far beyond my own beginner-level expertise here. Maybe there's a one-time-turner way of getting the conflicting gliders past the already-built pseudo-AC pairs, to use the below-left recipe on all four sides?
...
If we only need that four ACs, this would suffice:

Code: Select all

x = 101, y = 33, rule = B3/S23

But it isn't compatible with the blocks, and putting them inside with some reaction happening in such an extremely cramped space is challenging.

Let's synthesize something else that may be easier. Here are partial synths for two oscs from Sokwe:

没想到你就这样和我们说再见了。你寒假还会回来吗?
(Didn't expect you saying goodbye this soon. Will you return on winter holiday?)
Possibly.
