Sure, I can do that (though I might not get around to it until the weekend) That'd be best represented as, what, for each unsynthed xs20 a list of the other unsynthed xs20 for which a synthesis would be implied if the first one were solved? (Basically the adjacency-list representation of that direc...

Can you give a brief summary of what's known, if anything, about these remaining 2^10+1 still lifes? For example, it looks like most of them don't have any soups on record, but a few of them do. The current crop is what's left after some repeated hammering with transfer.py. Therefore, new component...

It's interesting to see these small spaceships being activated by a singular glider, but when I posted the challenge I was thinking more on the lines of some huge spaceship like the boat burner or corder lineship, being activated by a tiny tiny glider, as in the engine gets built by it, or the engi...

You know, it does seem like there might be a little bit of hope for a Bellman rebuild of the second one of those sacrificial long ships, to get a fast color-changing reflector. Has anyone tried a Bellman run on this yet? Yes. I've previous set up Bellman searches that have treated both of the longs...

Welcome! This thread would go better in the Patterns subforum. There's somewhat of prior art for this, using *WSSes rather than Copperheads. Many Caterpillar-like ships depend on crawlers among stationary/moving objects that can produce an excess of gliders, but if the "crawlers" are actually just g...

Kazyan

As an observation, the restriction that there be no consecutive "B" gliders strongly resembles phinary rather than binary. I'm not sure if this has mathematical significance aside from more efficient compression of a recipe.

Besides RCT, I suspect that the next model of smallest-sawtooth will have to be some mechanism that allows a small <c/2 ship to burn a blinker puffer fuse.

It's cool how p30 technology allows for construction work that would otherwise require elaborate looparounds from obscure toolkits. I'm not the most familiar with the timing constraints of elegant weapons for a more civilized age, but it looks like you can get a signal out of the tail in a simpler w...
