Summary:

This puzzle consists of 6 pieces with 3 points to click, namely A,B and C.
Clicking one of these points flip 4 pieces to the other side of the arrow.
After 4 twists, pieces are at their original places but twisted by ∓120°.		→ [A4] →

Solved states:

This puzzle has 12 solved states.

Mathematical properties:

· The permutation group of pieces is the transitive subgroup of S6.
· Any piece can be at any of 6 places,can be fliped, and can be twisted by N×120°.
· Number of flipped pieces is always even.
Therefore, the total number of possible scrambles is (5!) ×(6^6)÷2 = 2,799,360.
