7.0.2

Summary:

As7.7.0, this puzzle rotates 3 of 6 pieces
around each of 4 centers, A, B, C and D.
While rotating around the center, each piece rotates also around
the line between the center of rotation and its own center.
So, after 3 clicks, all pieces are at their original place,
but flipped around this line.

Solved states:

This puzzle has these 6 solved states:

Mathematical properties:

· The permutation group of pieces is A6.
· Any piece can be at any of 6 places, and can have any of 6 orientations(2 flip states × 3 rotations) .
· The sum of twists has no restriction.
· Total number of possible scrambles is (6!)/2*(6^6)=16,796,160.
