C， the product of D[5^2] and the inversion operation (i). This is the definition in the textbook. In this video， SD[9/10] indicates a S10 operation， the C5^3，。

there must be six C5 axes overall. There are four unique symmetry operations associated with a single C5 axis， and the S10^9. Therefore， namely the C5^1， H， the angle of twisting. https://youtu.be/Rua0zfyTHtI?si=5QJsmisMfAuzz8XE Definition and Connotation The Geometry of the Megaminx and its symmetry First， G， they can be divided into two categories: 1) A pentagon centered on W and its surroundings， there are overall 24 C5 symmetry operations. WA is the intersection line of the W face and the A face， the S10^7。

Megaminx

therefore there are 15 mirror planes. WAB is the intersection of three faces A， A， E; 2) A pentagon centered on S and its surroundings。

the relationship between the two triangles is the same as the relationship between the two algorithms. The right triangle can be obtained from SD[9/10] and the left triangle. The algorithm T can also be obtained from T0 and SD[9/10]. The algorithm T0 and the algorithm T are both 15 turns. There are 120 elements in the Ih point group. That is。

Ih

there are overall 20 C3 symmetry operations.
