Given its small recovery time, the snark made oscillators of previously unknown periods of 43 and 53 trivial, that was shown by [[Matthias Merzenich]] on the same day when it had been announced.

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.

It has been the outcome of the challenge, set by Adam P. Goucher in 2010, to complement a pattern, found by Dietrich Leithner about 1998.[1] The still life catalyst used in the snark 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.
