Year of discovery 2022

Raucci's p38 (also called 44P38) is a period-38 oscillator found by David Raucci on January 12, 2022[1]. It is the first finite oscillator of this period to be discovered. It consists of two wings being hassled by the traffic stop catalyst. The period-38 wing reaction was originally found in the form of an infinite wick by Jason Summers on August 31, 2000.

Its duoplet spark can reflect gliders in at least two ways, as shown by vivi[2] and Kalan Warusa.[3]

A 14-glider synthesis was found for this oscillator on the day of its discovery.[4]
