m removed reference to myself, as it was unimportant.
then the reference to calcyman is also unimportant ;)

The snark is a 90° stable glider reflector, made up of two eaters, a block and an unnamed 31-cell still life. It is currently the fastest and the smallest 90° stable glider reflector, both in terms of the population and the bounding box.

The reaction was discovered by Dietrich Leithner about 1998, but it consumed another block.[1] A catalyst that could replace the block was found with Bellman, a program for searching catalytic reactions, developed by Mike Playle.

Given its small recovery time, the snark made oscillators of previously unknown periods of 43 and 53 trivial.
