For the period-36 oscillator, see 22P36.

Jason's p22 (or 36P22) is an unnamed period-22 oscillator discovered by Jason Summers on August 27, 2000.^[1] It is composed of an unnamed reaction stabilized by two copies of eater 1. In terms of its 36 cells, it is the smallest known period 22 oscillator, followed by beacon on 38P11.1 and champagne glass with 40 and 45 cells, respectively.^[2] Later on the day of the oscillator's discovery, David Eppstein found a way to combine two of them to produce the first true period 22 gun.^[3] In February 2001 Jason Summers found a 12-glider synthesis of this oscillator,^[4] which was improved to 11 gliders by 2718281828 in December 2017^[5] and later 10 by Mark Niemiec in September 2019.^[6]
