42100M is a methuselah with a lifespan of 42100 generations, discovered by Dave Greene on October 31, 2018, using Adam P. Goucher's apgsearch and Catagolue tools.[1] Until the discovery of 42883M ("Homer"), it was the longest-lasting known methuselah to fit within a 16×16 bounding box, surpassing the 20×20 soup Wilma which was discovered by Rob Liston just three days earlier.
