The snark is a 90° stable glider reflector discovered by Mike Playle in April 2013.[1] It is made up of two eaters, a block and an unnamed 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.[2] A catalyst that could replace the block was found with Bellman, a program for searching catalytic reactions, developed by Mike Playle.

Given its small repeat time, the snark made oscillators of previously unknown periods of 43 and 53 trivial.[3]
