Achim's p16 is a period-16 oscillator that was found by Achim Flammenkamp on July 27, 1994.[1] With 32 cells, it was the smallest known period-16 oscillator until the discovery of Rob's p16 in 2020.[2] In October 2004 Jason Summers found a 12-glider synthesis of this oscillator.[3]
The first known semi-natural appearance of this oscillator was in November 2014 in a soup found by Dongook Lee using apgsearch.[4] 1 in 960,000 odd-width 90° symmetric soups (C4_1) form an Achim's p16.
