I'm Matt McIrvin--I've been interested in Life and cellular automata in general ever since the 1980s, brought in by columns by Martin Gardner, Douglas Hofstadter and A. K. Dewdney in Scientific American, and William Poundstone's pop book The Recursive Universe (in which he covered topics like a ...

I *thought* I saw the remains of an oblique puffer in one of my b37e/s238 soup runs; I guess I wasn't hallucinating.

This seems to me to actually be a stable rule, at least in practical terms, but it is remarkably close to the edge of explosion, closer than b37e/s23. And, yes, in my enthusiasm ...

Oh, my, that's an interesting one. Seems to be a just barely stable rule, or on the edge.

Naturally occurring diagonal loaf-and-block maker, b37e/s238:
I think there's a knightly one too.

The explosiveness of B37/S238 makes it harder to find stuff in debris, but with low-density soups it's possible to detect short-term patterns. Soups produce many flower gardens like B37/S23 and super beehives like B3/S238, also the "barge siamese loaf".

Pulsars do appear though they seem not as ...

After perturbation, the spark emits two gliders, one of which interacts with a block. That collision releases an explosion which interacts with the puffer in the same way that the R-pentomino did with WhiteHawk's isolation.

So one of those gliders emitted in the diagonal reverse directions from ...

Indeed, though if anything, B37/S238 is slightly more explosive than B37/S23, not less.

B37/S238 is an explosive rule generally very similar to DryLife, B37/S23. It supports many of the same notable patterns as DryLife, such as its puffers and its p60 glider gun. It seems to burn slightly "hotter".

Over the years, people here have occasionally mentioned its most salient feature, which ...
