Block is an extremely well-known and common still life that was found by John Conway in 1970. In terms of its 4 cells it is tied with tub as the smallest still life, and in terms of its 2-by-2 bounding box it is the outright the smallest. It is also the most common still life, occurring almost twice as often as beehive, the next most common still life.[1]
The block was one of the patterns described in the original 1970 article by Martin Gardner that introduced the Game of Life to the world.
