Raucci's p102 is a period-102 oscillator found by David Raucci on May 25, 2022. It consists of an active region shown below being hassled by two unices and two fishhooks; the fishhooks use the tail catalysis. It is the smallest known period-102 oscillator, having 67 cells.

It can be synthesized in 17 gliders. Each unix takes five, each fishhook takes two, and the active region takes three.

The active region, shown in the gallery below, has also been used in a small p25 and 44P49.
