Noah's ark is a diagonal puffer that was found by Charles Corderman in 1971. 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.
