WebMar 12, 2024 · 3 The Shephard Groups of Tetrahedral Type. From now on, the presentation of each primitive complex reflection group of rank 2 will be kept as usual in [ 12, 17 ]. We recall that a Shephard group is the symmetry group of a regular polytope, that is, the reflection group associated to a Coxeter diagram without branch. 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.
