112P57 is a period57 oscillator. It is currently the smallest known oscillator of this period.
The engine was first found in a larger form shown below by Mitchell Riley on September 23, 2022. On May 18, 2023, iNoMed reduced the large period3 oscillator to one with only 19 cells, making it the smallest known period57 oscillator by population.
The active region is an Rturner without its first blinker. Unusually, a lone ship works as a catalyst on this region.
On June 24, 2023, Chris857 found a 136glider synthesis.^{[1]}^{[2]} In July, 2023, the cost of a still life used in the construction was reduced, yielding a 134glider synthesis,^{[3]} and then another reduction that same month reduced the cost to 132 gliders.^{[4]}^{[5]} In November 27, 2023, KtT reduced the cost to 130 gliders.^{[6]}^{[7]}
