49768M is a methuselah with a lifespan of 49768 generations, discovered by Rob Liston on April 21, 2020, using apgsearch. On April 24, Goldtiger997 found a variant of this methuselah which lasts one generation longer while still fitting within the same bounding box, which is currently the longest-lasting known non-infinitely-growing methuselah within a 16×16 square. Both of these surpass 47575M which was discovered in February 2019.
