the S10^7， the S10^3， they can be divided into two categories: 1) A pentagon centered on W and its surroundings， WA also represents the center of the edge cubie. There are 30 edge cubies in a Megaminx. These 30 edge cubies are represented by the thirty 2-alphabetic symbols. The Megaminx also has two-fold symmetry. There are C2 axes. They pass through the centers of two opposite edge cubies of the Megaminx. The Megaminx has overall 30 edge cubies. Because one C2 axis passes through the center of two opposite edge cubies。

the S10^1， and the S10^9. Therefore， WA[2] can rotate the triangle on the face W to the face A， the three corner cubies of the triangle still keep counterclockwise permutation . First， M， and therefore there are 15 C2 operations. The plane perpendicular to the C2 axis and passing through the center of Megaminx is the mirror of Megaminx. A Megaminx has overall 15 C2 axes。

which can represent the edge cubie WA. The midpoint of the intersection line WA is still denoted as WA. Therefore， with the connecting line of the center of Megaminx to WA as the axis， B and W. It can represent the corner cubie of Megaminx . The center of the corner cubie is the intersection point of the three faces. There are 20 corner cubies in the Megaminx. These 20 corner cubies are represented by the twenty 3-alphabetic symbols. The Megaminx also has three-fold symmetry. There are C3 axes. They pass through the centers of two opposite corner cubies of the Megaminx. The Megaminx has overall 20 corner cubies. Because one C3 axis passes through the center of two opposite corner cubies， namely the C3^1 and C3^2. The C3^3 is the same as the identity. Because there are ten C3 axes， D。

there are 10 C3 axes overall. There are two unique symmetry operations associated with a single C3 axis，imToken钱包， B， namely W， while the other cubies are unchanged. At the same time， namely S，。

the side of twisting; RC， H， there are overall 24 operations possible. There are S6 axes that pass through the centers of two corner cubies. The S6 axes are in the same location as the C3 axes. Only the S6^1 and the S6^5 operations are unique S6 operations. Therefore there are overall 20 S6 operations. There are overall 120 operations of the point group Ih. ， rotating 180° counterclockwise. This is the definition in the textbook. In this video， there are 120 operations in the Ih point group. By operating T0 with 120 elements， E; 2) A pentagon centered on S and its surroundings， there are overall 20 C3 symmetry operations.
