We are finding that some of the numbers are 1 away from the winning numbers; either +1 or -1 in the group-set of numbers: Repeat, Once, or Invert.

If a group-set of numbers can be shifted left or right by either adding 1 or subtracting 1.

Also, the 0 and 9 loop around when doing this shift.

As an example, if the group-set were (0 1 2)-(3 4 5 6)-(7 8 9) and we added 1 to the set, it would become (1 2 3)-(4 5 6 7)-(8 9 0); where the 9 becomes 0 by looping back around.

Likewise, if the group-set were (0 1 2)-(3 4 5 6)-(7 8 9) and we subtracted 1 to the set, it would become (9 0 1)-(2 3 4 5)-(6 7 8); where the 0 becomes 9 by looping back around.
