An unexpected result from trying to build an R-to-X:

Also, I really think that a spaceship is possible out of this. (5,14x)c/102 Herschel reaction, (it is also a [H5,6xB]c/82 reaction) triplicating the input glider into an extra block and two gliders, one forward and backward:

It may not be oblique, but I would love to work on it. It has probably been discovered before. I might try to find a helix (is there such a search program?)

The helix program written by codeholic for caterpillars is here. The climb is slow enough that the helix should be plenty short at N=1.

One considerable difficulty with building a caterpillar with that is that the streams need to be synchronized from left and right. That means that each climber puts a large demand on the structure. Most important in design would probably be finding a single reburnable element made of a collection of these climbers.

This problem is resolved by adding 1 glider:
This can actually be done without the extra glider, by using a different 2-glider B-heptomino generator. Also, this general mechanism was already known, although the two essential cleanup gliders hit slightly differently, and resulted in forming the same Unix, but in a slightly different way, and a different phase:

While the six-glider synthesis is usually optimal, this mechanism does have one advantage, in that it forms the Unix in the corner, making it more conducive to syntheses where a Unix needs to form in close quarters with something else being formed at the same time (e.g. Unix on complex still-life) or two siamese Unices, e.g. from a pre-existing long barge.

Here's a strange little reaction:

\$14.C!``````
The sacrificial block would be replaceable with an ordinary fishhook or eater2, except that the reaction sticks around for a bit. A catalyst with a large (9 or more generations) recovery time could make this into a mini-rectifier, if it has a low enough profile to not be destroyed by nearby sparks. I haven't found any results with Bellman yet, though (max-active = 9, recovery = 30)

A sacrificial mango (pointing southwest/northeast) also works for the reaction, and produces a phi spark. Restoring the mango might not be a very promising search, but it drags the catalysis action away from the main reaction.

It's too bad a hive or loaf can't be used, and that boats, ships, and blocks produce no workable side reaction.

Anything's possible, of course. But for similar reasons to the ones given here, I wouldn't say it's a likely line of investigation.

If you only had to use catalysts to tame the junk and restore the block, maybe that would be worth a try with a search program. But to restore the block, and simultaneously restore the loaf (or whatever object created a similar spark)... well, that would take a lot more beginner's luck than I probably have left. Your mileage may vary, of course.

-- I bet we're at the point where a distributed search using some kind of catgl / ptbsearch / CatForce / Bellman variant would eventually turn up a direct Herschel-to-spaceship converter. The main thing is to set up the program to recognize *WSS outputs reliably, instead of just adding more catalysts to kill them off.

Beyond that, it's just a matter of generating a huge variety of configurations that might possibly be viable catalysts, and testing them automatically. As Catagolue has shown, the weight of probability will do the rest sooner or later -- there are a lot of spaceships out there.

Might even dig up a Herschel-to-swimmer conduit eventually, with the same program (sadly, Herschel-to-loafer is probably too much to hope for...)

Posted: October 3rd, 2015, 9:51 pm
I wasn't expecting a stable object to produce the junk. I was saying that it might be possible to rig up some other connection to a Herschel that produces the junk. Having to restore another still life is obviously not going to work.

The loaf reaction was only shown as the original "accidental discovery" and I do not think that what you thought I wanted is in any way a good idea at all.
