23334M is a methuselah with a lifespan of 23334 generations that was found by Tomas Rokicki on February 20, 2005. It is notable because it is one of very few patterns to naturally emit a lightweight spaceship during the course of its evolution.
The stable pattern that results from 23334M has 2898 cells and consists of 207 blocks, 171 blinkers (including 14 traffic lights), 115 beehives (including six honey farms), 70 gliders, 32 loaves, 23 boats, seven tubs, six ships, four ponds, two long boats, two beacons, one toad, and one lightweight spaceship.
