p26 glider shuttle is a period-26 oscillator based on a dependent period-26 reflector, discovered by Matthias Merzenich on February 19, 2012.[1] It was the smallest known period-26 oscillator in terms of minimum population until the discovery of 87P26 on August 7, 2015.

Jeremy Tan found an 84-glider synthesis for this oscillator on June 7, 2019.[2]
