- A cellular automaton is said to be omniperiodic if it has oscillators of all periods. Conway's Game of Life is omniperiodic, since there are oscillators of every period, with the last found period being p41 in July 2023.

Dec 5, 2023 · At the turn of the millennium, only twelve oscillator periods remained to be found in Conway's Game of Life. The search has finally ended, with the discovery of oscillators having the final two periods, 19 and 41, proving that Life is omniperiodic.
Conway’s Game of Life is a cellular automaton occurring on an infinite plane of square grid cells, each of which is in one of two states: alive or dead. The neighbourhood of a cell is the 8 cells that are connected orthogonally or diagonally to it.
Dec 13, 2023 · This proves once and for all that the Game of Life is indeed omniperiodic. Mitchell and co’s paper describes all 43 of these oscillators along with the techniques that computer scientists and mathematicians have developed to find them and build ever more capable oscillators.

In October 1996, David Buckingham wrote the article My Experience with B-heptominos in Oscillators that describes his discovery of Herschel conduits, including sufficient stable conduits to enable, for the first time, the construction of period n oscillators for every n ≥ 58, and true period n guns for every n≥ 62. The discovery of the Snark by Mik...
By running Dean Hickerson's drifter searcher to find signals that can be manipulated like Herschels, it is possible to prove that a variety of Life-like cellular automata are omniperiodic. However, these signals are more like the 2c/3 signal, in that they operate on a dense background and can closely follow each other. There is a significant possib...

Sep 21, 2024 · 204P41 is a period-41 oscillator found by Nico Brown on July 21, 2023, and is the first period-41 oscillator to be discovered. [1] [2] Its discovery proved that Conway's Game of Life is omniperiodic. It was originally found as 208P41, and the blinker eaters were quickly reduced by two cells each.
