35201M is a methuselah with a lifespan of 35201 generations, discovered by Andrzej Okrasinski on September 4, 2008 as part of his census. It was rediscovered and reported on the ConwayLife.com forums by Lewis on March 28, 2010.

Adam P. Goucher, Dave Greene and Matthias Merzenich proposed various modifications of 35201M to reduce its initial population, including:

Stable pattern

The stable pattern that results from 35201M (excluding 85 escaping gliders and one escaping lightweight spaceship) has 5391 cells and consists of 401 blinkers (including 38 traffic lights and one interchange), 380 blocks, 232 beehives (including eight honey farms), 82 loaves, 70 boats, 23 ships, 11 tubs, ten ponds, four beacons, three ship-ties (two of which are in the form of a fleet), three toads, two barges, two long boats, and one beacon.
