p196 pi-heptomino hassler is a period-196 oscillator completed by praosylen on July 2, 2021 based on a partial result by David Raucci. It consists of two rotationally symmetric pi-heptominoes interacting with each other in addition to hitting block and eater 2 catalysts. After a half cycle, it flips along a diagonal axis. At 66 cells, it is the smallest known period-196 oscillator by population.

Within a few hours of its discovery, Jeremy Tan found a 24-glider synthesis of the oscillator.

LCM oscillators

The LCM 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.
