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. Half of this oscillator can be replaced by a toaster, as shown below.
