Noah's ark is a diagonal puffer that was found by Charles Corderman in 1971.[1] It consists of two mutually stabilizing switch engines and is thus an ark. Its name comes from the variety of objects it leaves behind - in particular, every 1344 generations it produces 42 blocks, 40 blinkers, 22 beehives, eight loaves, four gliders, two boats, two block on tables, two long boats, two ships, and one beacon.
A 3-glider synthesis of a switch engine discovered by Luka Okanishi in March 2017 allowed for a 6-glider synthesis of Noah's ark.
