Suppose A and B are streams of gliders, as usual, a glider denotes a 1, the absence of a glider a 0. |
We show that if either A and B (or both) have a 1 in the current location, then A or B will have a 1 in that location. |
Only if both A and B have a 0 in the current location will A or B have a 0. |
Note that since B interacts with the glider stream later than A does, the B stream must lag behind the A stream. |
Return to the or operation.
