50093M is a methuselah with a lifespan of 50093 generations, discovered by Rob Liston on January 9, 2021, using apgsearch.[1] The same day, goldenratio used LogicLifeSearch to find a variant (50095M) of this methuselah lasting two more generations,[2] 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.[6] 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.

Notes

  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;[3] however, this is often not counted as a methuselah.[4] Another soup, based on a crystal reaction, was found by Liston on May 29, 2020 lasting 10,514,926 generations.[5]
