Riley's p19 is the first period-19 oscillator to be found, and was discovered by Mitchell Riley on July 14, 2023, assumedly using CatForce (similarly to the oscillators discovered in the mvr_catforce_stdin census).[1]
On the day of its discovery, iNoMed reduced its minimum population from 100 to 96, then to 94,[2] then May13 reduced it to its current minimal known form of 92.[3] Each reduction was made by replacing its stators with smaller components.
