The universal cellular automaton emulating one step in the evolution of the rule shown above, which involves next-nearest as well as nearest-neighbor cells. The rule now covers a total of 32 cases, corresponding to the possible arrangements of colors of a cell and its nearest and next-nearest neighbors. The picture shows the evolution of five cells according to the rule shown, with each cell now being represented by a block of 70 cells in the universal cellular automaton.
