My experience is that the wrap around is common, as otherwise the hard edge causes a discontinuity in the rules at the edge, so any pattern that reaches the edge no longer has a valid result. The torus effect still perturbs the result, but that perturbation is effectively that the universe was tiled with an infinite grid of the starting pattern, so represents a possible universe. -- Richard Damon -- https://mail.python.org/mailman/listinfo/python-list
