[Reverse] Crazy, <N/4> [Reverse] Crazy

Crazy causes the call to be performed on each side, then by the (new) centers, then on each side again, and then by the centers again. It has 4 parts. When there is a choice, the splitting is into 2x2 boxes rather than 1x4's. Reverse Crazy starts in the center, then each side, then in the center, and then each side. Both of these can be fractionalized. 3/4 Crazy means each side, centers, and each side. 3/4 Reverse Crazy means centers, each side, and centers. When fractionalized, the result has that many parts.

The word order "Reverse 3/4 Crazy" used to be commonplace, but there are now those who frown upon it. In any case, it means the same thing as the other order.
