Sphere

A sphere is a possible finite Life universe in the form of a sphere. The simplest way to do this is to use an m × n rectangle with the top edge joined to the left edge and the bottom edge joined to the right edge. It is similar to the torus except that it has adjacent pairs of sides joined instead of opposite pairs. at the corners, things behave strangely.
