Notes: A rule set that (very probably) results in explosive growth; certainly in area if not population.

For example, putting a 1 at (0: 1,1) will cause explosive growth in all directions, putting a 1 at (0: 0,2A) will cause pairs of diagonal cells in a 2x2 square to alternate on and off, putting a 1 at (1: 4,4) will cause all solid 1 areas to stay 1 for another cycle, etc.

If the rule is further chosen so that active cells can (and must) expand on an inactive background but inactive cells can't do so on an active background (or vice versa), then non-explosive growth becomes possible.
