42P10.3 is an unnamed period-10 billiard table oscillator. It was the first period 10 oscillator to be found, and was discovered by David Buckingham no later than 1976.[1] It uses a block as an induction coil. This oscillator is related to 54P17.1.
In September 2015 Martin Grant found a 251-glider synthesis for a stator variant of this oscillator (Catagolue: here).[2] On July 8, 2024, vilc found a 78-glider synthesis of the canonical version.[3][4]
