Period-22 glider gun is a true period 22 gun discovered by David Eppstein on August 27, 2000. It uses two copies of the period 22 oscillator, 36P22, and was in fact found later on the same day as that oscillator. It is one of a relatively small number of known true period guns below period 78, where syringe-based guns become possible.
