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 was formerly 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, but have since been surpassed by 52513M which was found just a week later on January 16, 2021.
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.
