66P106 is the smallest known period-106 oscillator. The original form, 115P106, was discovered by Nico Brown on October 1, 2022.[1] It consisted of an unnamed active region being hassled by two traffic stops, two catalysts that are present in AK94, and four eater 1s. On September 24, 2023, Carson Cheng found a period-2 traffic light catalyst consisting of a toad, a clock, and a transparent blinker, which iNoMed used to reduce the oscillator from 115 cells to 66. Even at 115 cells, it was still the smallest known period-106 oscillator.
The active region is mentioned without a name in Lifeline Volume 8, page 5.
With regard to the original 115-cell form, a 60-glider synthesis for 115P106 was found by Chris857 on the day after its discovery[2] which was then improved to 58 gliders.[3] Chris857 also synthesized a smaller and cheaper variant that has two fumaroles at both ends;[4] they remove blinkers with their domino sparks, but increase the overall period to 106 × 5 = 530.
