Century is a hexomino. It is a common methuselah that evolves into three blocks and a blinker after 103 generations. It produces a temporary toad at generation 59 which is destroyed at generation 79.

David Buckingham built a period-246 glider gun using a century as the engine in June 1996.

It is a parent of the bookend.

Century eater

Century can be eaten by a configuration of three eater 1s surrounding a beehive, as shown below. A much smaller century eater was found by Ivan Fomichev in 2013.[1] Both of them play a prominent role in the bistable switch.
