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. It is a parent of the bookend.
Century can be eaten by a configuration of three eater 1s surrounding a beehive, as shown below (century is upper-right in each case). A much smaller century eater was found by Ivan Fomichev in 2013.[1] Both of them play a prominent role in the bistable switch.
Century collisions with a block, where the century gets eaten.[2] Note that they are of lower clearance, so the larger century eaters generally tend to be more useful. (click above to open LifeViewer)
