| Here is an example of an Outer Totalistic rule for a von Neumann neighborhood with two configurations selected. |
| * In the first, the central cell is alive and one of the four surrounding cells is alive. There are four nbhd configs of this type, indicated by the blue pictures on the right. |
| * In the second, the central cell is dead and two of the four surrounding cells are alive. There are six nbhd configs of this type, indicated by the red pictures on the right. |
|
| This outer totalistic configuration describes the CA in which any of these ten nbhd configs gives rise to a live cell in the next generation. |
