Re: Unlisted Methuselah, Hexomino?

General rule of thumb: if you have a new methuselah and it's 1) under 8 cells, it's already known 2) under 1500 generations, we don't care That said though, listing some sort of Common Precedessors tables on the wiki might be a good idea. I've got decent-sized collections for a few of them (R ∏ LoM ...

Re: 238/346/3

I need a name for this rule as well, anyone have any suggestions? I've explored the related rule 238/3478/3, which I've dubbed "tubnificent". x = 3, y = 3, rule = 238/3478/3 .A$A.A$.A!

Re: 4c/83 growing wick (p150)

I would call this a slidegun rather than a wick. A slidegun is supposed to shoot a spaceship, and this pattern doesn't. …slidefactory, then? Or maybe we could consider this a fuse that burns on a moving medium — the burning reaction proceeding downstream at 75c/166, but since the fuse body itself k...

Re: 4c/83 growing wick (p150)

I would call this a slidegun rather than a wick. Wicks in the usual sense involve an oscillator or spaceship component that needs a copy of itself on two sides for stability.

Though since the reaction here needs continuous support, you might also call this a "puffer pushalong". :)

Sure.

Re: It´s not a Gosper Glider Gun !

In the case of your gun, there are basically three mechanisms involved: 1) the glider-producing interaction of two queen bee shuttles (found by Gosper 40+ years ago), 2) the block eating the beehive (also from the same time period), and 3) the two shuttles colliding to avoid dropping beehives.

Re: Alternating rules

For a benchmark, a trivial solution can use three rules alternated and two survival conditions overall:
1) A/S
2) A/S
3) B3/S23

Things probably get harder if using B0 is disallowed.
