- For the period 22 oscillator, see 36P22.
22P36 is an unnamed period 36 oscillator found by Noam Elkies on January 29, 1995. It consists of a double hassling action, in which two colliding traffic lights is first converted by eater 1s into two pair of blinkers and a two blocks. These react to create a pair of blinkers and L-sparks, which then produce then a pair of phi sparks, which are then hassled by the same eaters to produce T-tetrominoes, which re-evolve to traffic lights. In terms of its 22 cells it is the smallest period 36 oscillator.
