115P106 is the smallest known period-106 oscillator, discovered by Nico Brown on October 1, 2022. It consists of an unnamed active region being hassled by two traffic stops, two catalysts that are present in AK94, and four eater 1s.

A 60-glider synthesis for 115P106 was found by Chris857 on the next day which was then improved to 58 gliders. Chris857 also synthesized a smaller and cheaper variant that has two fumaroles at both ends; they remove blinkers with their domino sparks, but increase the overall period to 106 × 5 = 530.
