List of common still lifes

From LifeWiki
Jump to: navigation, search

This is a list of the most common still lifes in the Game of Life, specifically Catagolue's B3/S23/C1 census. The minimum known glider synthesis, as of July 2019, of each still life is also displayed. The "approximate relative frequency" column gives an estimate of the proportion of all randomly-occurring still lifes that will be of the given type.

This table only includes strict still lifes and thus does not count objects like honey farms.
