WebBinary tetrahedral group We consider a tetrahedron consisting of vertices . (1) Since vertex symmetry has order 3, each vertex symmetry has two angles and and the union of lifts of vertex symmetries is Thus, we have (2) As the edge symmetry has order 2, each edge symmetry has only one angle so that the related lift is and the union is given as Webfor the binary tetrahedral group. 1. The binary tetrahedral group Let T 0 ⊂ SO(3) denote the symmetry group of a regular tetrahedron. The preimage of T 0 under the standard homomorphism SU(2) → SO(3) is the binary tetrahedral group T. As an abstract group, T is the semidirect product of the quaternion group Q 8 = {±1,±I,±J,±K} and the ... dhcd action plan
