Math of Rubik Cube:Megaminx=Ih Point Group: (36): SA[1/10]
李世春 2024-7-17 07:57
SA indicates a S10 operation, the product of A and the inversion operation (i). This is the definition in the textbook. In this video, SA can operate the triangle on the face W to the face D, while the other cubies are unchanged. However, the counterclockwise permutation of the triangle ...

The Megaminx = Ih point group (30/120)
李世春 2024-5-31 12:19
I found 120 algorithms for the Megaminx based on the Ih point group. In turn, these 120 algorithms can represent the Ih point group. For example, if B1W3B1A1B4W4B4W1B1A4B4W4B1W3B4 represents e, then C1W3C1B1C4W4C4W1C1B4C4W4C1W3C4 represents W . Therefore, there are 1 ...
