55P10 is a period-10 sparker that was found on December 27, 2018 by Bullet51. The version shown in the infobox is a stator reduction found by Matthias Merzenich three days later. A skewed variant can be made by moving the right side down two cells and extending the left side of the gutter by two cells. On March 22, 2019, Tanner Jacobi used this oscillator to construct smaller p50, p100, and p200 glider guns.
