Cribbage, or Riley's p19, is a period-19 oscillator found by Mitchell Riley on July 14, 2023 using CatForce, and was the first period-19 oscillator to be discovered.[1]
On the day of its discovery, iNoMed discovered a pair of successive stator reductions over the original form (first to 96 cells, then to 94),[2] which was subsequently reduced by May13 to a 92-cell form.[3] Each reduction was made by replacing its stators with smaller components.
A 69-glider synthesis of a 100-cell variant of the oscillator was found by Goldtiger997 on the same day.[4]
The name "cribbage" comes from the card game, where 19 is a significant number and somewhat of a meme in the game, being the smallest number of points that is impossible to get in a single round.

LCM oscillators
Cribbage can form LCM oscillators via either several low-clearance sparks or a billiard table perturbation of one of the large catalysts.
