98P25 is an unnamed period-25 oscillator discovered by Noam Elkies in October 2002. In terms of minimum population, it was the smallest known period-25 oscillator until the discovery of an improved version of the pattern.
It works by using four fumaroles and two blocks to hassle two honey farm predecessors.
