Simkin glider gun/Snippet
Simkin glider gun is a glider gun, found by Michael Simkin on April 28, 2015. It consists of a Herschel running in two period-60 conduits, producing infinite copies of the first natural glider. In terms of its 36 cells single-barreled form it is the smallest known gun, sharing the record with the Gosper glider gun. Moreover, in the double-barreled (29 cells), as well as the pseudo-period, boat-bit form it is the absolute record holder.
