'''Simkin glider gun''' is a glider gun, found by [[Michael Simkin]] on April 28, [[:Category:Patterns found in 2015|2015]]. It consists of a [[Herschel]] running in two period-60 [[conduit]]s, producing infinite copies of the [[first natural glider]]. In terms of its 36 cells it is the smallest known gun, sharing the record with the [[Gosper glider gun]]. In the 29-cell [[double-barrelled]] form, as well as the [[pseudo-period]] [[boat-bit]] form, it is the absolute record holder. Its smallest known predecessor has only 21 cells.

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 (by supressing one of the 2 streams using an eater 1) it is the smallest known gun, sharing the record with the Gosper glider gun. In the 29-cell double-barrelled form (shown in the infobox), as well as the pseudo-period boat-bit form, it is the absolute record holder. Its smallest known predecessor has only 21 cells.

The day of its discovery, Chris Cain used it to create a sawtooth pattern with 181 cells.[1]
