Jason's p22 gives off [[spark]]s, which in addition to allowing for the construction of non-trivial higher-period oscillators as seen in a [[#LCM oscillators|later section]], can be used to [[hassle]] various patterns shown in [[#Gallery|gallery]] below. 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|true]] [[period-22 glider gun]].

This article is about the 36-cell period-22 oscillator. For the 22-cell period-36 oscillator, see 22P36.

Jason's p22 (or 36P22) is a period-22 oscillator discovered by Jason Summers on August 27, 2000.[1] In this oscillator, an unnamed reaction is stabilized by two copies of eater 1. In terms of its 36 cells, it is the smallest known non-trivial period-22 oscillator, followed by p22 honey farm hassler with 40 cells, a p22 pi-heptomino hassler with 42 cells, and champagne glass with 45 cells.[2]

Jason's p22 gives off sparks, which in addition to allowing for the construction of non-trivial higher-period oscillators as seen in a later section, can be used to hassle various patterns shown in gallery below. 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 glider gun.

On August 12, 2022, this oscillator appeared semi-naturally for the first time, in a symmetric soup found by the Open Science Grid.[3]

Glider synthesis

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 to 10 gliders by Mark Niemiec in September 2019.[6]

LCM oscillators

The LCM oscillators below are the smallest known ones by population while satisfying the condition that at least one cell oscillates at the full period.
