Goban is a period-19 oscillator, and is the second period-19 oscillator to be discovered, after Cribbage. It was found by Period1GliderGun on January 24, 2024, as a completion of a period-19 wick by May13, which was itself a stabilisation of a partial by iNoMed for which Period1GliderGun had previously found a period-38 stabilisation. On the same day, BlinkerSpawn reduced its stator by two cells, yielding its present minimum population of 134.

May13's wick stabilisation (click above to open LifeViewer)

Etymology

It was named after the goban (transliteration of 碁盤), the board upon which the game of Go is played, due to the early history of Life involving the manual simulation of patterns upon them, and as a reference to the fact that they are traditionally 19 × 19.
