character table of 2T

linear representation theory of binary tetrahedral group 2T2 T


group order: |2T|=24\vert 2T\vert = 24

conjugacy classes:1-1iiabcd
their cardinality:1164444


let ζ 3\zeta_3 be a third root of unity, (ζ 3) 3=1(\zeta_3)^3 = 1

e.g. ζ 3=12(1+3i)\zeta_3 = \tfrac{1}{2}(-1 + \sqrt{3} i), notice that ζ 3+ζ 3 2=1\zeta_3 + \zeta_3^2 = 1
