50093M is a methuselah with a lifespan of 50093 generations, discovered by Rob Liston on January 9, 2021, using apgsearch. The same day, goldenratio used LogicLifeSearch to find a variant (50095M) of this methuselah lasting two more generations, which is currently the longest-lasting known non-infinitely-growing[note 1] methuselah within a 16×16 square. Tanner Jacobi found another variant which does not fit within 16×16 but has a population of only 59 cells. All of these surpass 49768M which was discovered in April 2020.
The stable pattern that results from 50093M (excluding 118 escaping gliders) has 5593 cells and consists of 369 blinkers (including 32 traffic lights and one interchange), 348 blocks, 220 beehives (including eight honey farms), 62 loaves, 54 boats, 26 ships, 19 tubs, 15 ponds, five toads, five long boats, two ship-ties in the form of a fleet, two beacons, one barge, one mango, and one eater 1.
- ↑ An infinitely growing soup which "goes boring" after 133100 generations due to a backwards-firing stream of gliders was found by Rob Liston on May 12, 2019; however, this is often not counted as a methuselah. Another soup, based on a crystal reaction, was found by Liston on May 29, 2020 lasting 10,514,926 generations.
