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.[1][note 1] The improved version, found by Matthias Merzenich on January 10, 2016, replaces the west and east fumaroles with eater 1s.[2]
104P25,[1] the original form of the oscillator that uses two copies of eater 1 rather than blocks (shown with highlighted envelope) (click above to open LifeViewer) RLE: here Plaintext: here Catagolue: here |
It works by using four fumaroles and two blocks to hassle two honey farm predecessors.
A slightly smaller version, 88P25 (click above to open LifeViewer) RLE: here Plaintext: here Catagolue: here |
Half of this oscillator can be replaced by a toaster, as shown below.
105P25, a related period-25 oscillator that hassles only one honey farm predecessor (click above to open LifeViewer) RLE: here Plaintext: here Catagolue: here |
