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]
