46P10 is a period-10 oscillator found by Nicolay Beluchenko on March 16, 2009.[1] It can be seen as two unices sharing blocks. Four clocks are used to prevent unwanted births on the edges.

A 41-glider synthesis of this oscillator was known in 2015.[2] A 40-glider synthesis was found in July 2023.[3] On February 8, 2024, KtT lowered the cost to 38 gliders.[4][5] On February 21, 2024, Daniel Vargas lowered the cost to 36 gliders.[6][7]
