22P36 is an unnamed period36 oscillator found by Noam Elkies on January 29, 1995.^{[1]} It consists of two ttetrominoes being hassled by two eater 1s. The eaters convert two traffic lights into two phi sparks, and then convert them back to ttetrominoes. In terms of population it is currently the smallest period 36 oscillator.
It first appeared seminaturally in July or August 2017, in a symmetric soup submitted to Catagolue by Moth Wingthane.^{[2]}
