Any pattern that vanishes, but only after a long time. The
following example vanishes in 130 generations, which is probably the
limit for patterns of 7 or fewer cells. Note that there is no limit
for higher numbers of cells. E.g., for 8 cells we could have a
glider heading towards an arbitrarily distant blinker.
Game of Life Explanation
The Game of Life is not your typical computer game. It is a cellular
automaton, and was invented by Cambridge mathematician John Conway.
This game became widely known when it was mentioned in an article
published by Scientific American in 1970. It consists of a grid of
cells which, based on a few mathematical rules, can live, die or
multiply. Depending on the initial conditions, the cells form various
patterns throughout the course of the game.
Rules
For a space that is populated:
Examples
Each cell with one or no neighbors dies, as if by solitude.
Each cell with four or more neighbors dies, as if by
overpopulation.
