it visits every possible state of the Cross Teaser that is reachable through legal moves, and does so through a BFS in order to prove the "diameter" (the smallest number of moves that allows solving the puzzle. note that:
- only states where the middle spot is empty are considered.
- only states reachable through legal moves starting from the solved state (where crosses are all equally oriented) are considered.
- a "move" is a combination of 4 cross moves, i.e. cycling 3 crosses (clockwise or counterclockwise).
- "solving" means the "stricter" notion, in which you need to get the 8 crosses to be equally oriented (but you're still free to choose what that common orientation is).

12 moves only solves 60% of the states.
13 moves solves 97%.
14 moves solves 99.99%.
15 moves solves 99.9999983%.
the diameter of the puzzle is 16 moves.
only 504 states require 16 moves (or more) to solve. because of cross rotational symmetry (there is no "base" orientation for the crosses) these reduce into 21 groups, reproduced below:

each line is a state, and lists the rotations of each of the crosses, in the following order:
each rotation is given as a 4-element permutation, where 0123
is the identity.
because each element represents a group of states, they've all been normalized so that cross 0 is always the identity.
