| Finally, suppose both A and B have 0s in the current location. |
| The hole in the A stream lets the glider from the glider gun stream through, so a 1 is transmitted to B. |
| But there is no glider in the B stream to be killed by the glider in the glider gun stream, so the current location of A and B is 0. |
| That is, if both A and B are 0, then A and B is 0. |
