Binary dihedral group
WebThe binary tetrahedral group 2T is a normal subgroup, as is Q8. The remaining elements are all of the form (1/√2) (±1±i) etc. The conjugacy classes are represented by 1, -1, i, and a = ½ (1 +i + j + k), c = ½ (-1 +i + j + k), e = (1/√2) (1+i), f = (1/√2) (-1+i), g = (1/√2) (i+j).
