The empty length 2 addresses are | The empty length 3 addresses are |
11 | 111, 112, 113, 114 (contained in 11) |
14 | 141, 142, 143, 144 (contained in 14) |

311, 314, 341, 344 | |
424 |
Note the pairs 42 and 24 are not forbidden, so the empty length 3 address 424 does not contain a forbidden pair. |
We see the exclusions of this driven IFS are not consequences of the forbidden pairs. More than the immediate past determines the future in this example. |
