Meatball is a period-7 oscillator found by Charity Engine on May 28, 2022. It bears similarity to 38P7.2 in terms of its ability to produce sparks, while having a slightly smaller bounding box.[1] It has been used to reduce multiple glider guns, specifically those of periods 21[2] and 49.[3]

LCM oscillators

The oscillators below are listed due to being the smallest known ones by population, while also satisfying the condition that at least one cell oscillates at the full period.[4]
