Figure eight on 22P36, not to be confused with figure eight on 36P22, is a period 72 oscillator composed of a figure eight and a 22P36 that was found on April 26, 2016. In terms of its 36 cells, it is the smallest known period 72 oscillator. It has one cell that oscillates at p72, and therefore is considered non-trivial.
