7468M is a methuselah with a lifespan of 7468 generations that was found by Tomas Rokicki on February 20, 2005. It is the longest-lived known pattern consisting of a single cluster with eight or fewer cells.

A 7-glider synthesis that converges at generation 4 and a 3-glider synthesis that converges at generation 26 are known.[1][2]

Stable pattern

The stable pattern that results from 7468M has 952 cells and consists of 61 blinkers (including 5 traffic lights), 51 blocks, 35 beehives, 24 gliders, 16 loaves, 11 boats, four ships, two tubs, two ponds, one toad, and one paperclip.[3]
