I wanted to try this puzzle ever since I have made the Constellation Six.The point was to get regular pentagons instead of circles in the face centers.
This was only possible by changing the angle between axes from 120° to 130.42°.
As a cost, the puzzle has lost its rotational symmetry and one working axis.
So, here's the Biaxe ([bi-'aks]) - a challenging puzzle with only 2 possible moves.
I don't know whether it is easier than Constellation Six, maybe the difficulty is pretty much the same.
Because there are 2 moves, a binary code notation may be used for scramling and solving: 00111000100101010100010
