namely W， therefore there are 15 mirror planes. WAB is the intersection of three faces A， there are 120 operations in the Ih point group. By operating T0 with 120 elements， the relationship between the two triangles is the same as the relationship between the two algorithms. The right triangle can be obtained from WEA[3^1] and the left triangle. The algorithm T can also be obtained from T0 and WEA[3^1]. The algorithm T0 and the algorithm T are both 15 turns. There are 120 elements in the Ih point group. That is， namely S， H， 120 new algorithms can be obtained. These 120 algorithms can generate 120 triangles distributed on 12 faces of the Megaminx . The meaning of other symbols: N。
