The AK-47 reaction, found by Rich Schroeppel and David Buckingham, is a reaction in which a honey farm predecessor catalysed by an eater 1 and a block reappears at another location 47 generations later, having produced a glider and a traffic light. This is the basis of a very small (but pseudo) p94 glider gun found by Paul Callahan in July 1994, and was the basis for Dean Hickerson's construction of the first true p94 gun in 1990 (this latter gun was enormous, and has now been superceded by comparatively small Herschel loop guns).

See the patterns P94S and P94S2 (on the same page) to see Dean Hickerson's huge gun and a later improvement, respectively.

On May 9, 2013 Mike Playle found a tiny true period-94 gun, AK-94.
