WebSince the group of unit quaternions is the double cover of the 3d rotation group, there are 2 12 = 24 unit quaternions that give rotational symmetries of the tetra-hedron. These form a group usually called the binary tetra-hedral group. (In case you’re wondering, the binary tetrahedral group is not WebIn some sense this reduces the classification of these groups to the classification of p -groups. Some of the small groups that do not have a normal p -complement include: Order 24: The symmetric group S 4. Order 48: The binary octahedral group and the product S4 × Z2. Order 60: The alternating group A 5.
WebBinary tetrahedral group We consider a tetrahedron consisting of vertices .
