Present data on neutrino masses and mixing favor the highly symmetric tribimaximal neutrino mixing matrix which suggests an underlying flavor symmetry. A systematic study of non-abelian finite groups of order g ≤ 31 reveals that tribimaximal mixing can be derived not only from the well known tetrahedral flavor symmetry T ≡ A4, but also by using the binary tetrahedral symmetry T' ≡ SL2(F3) which does not contain the tetrahedral group as a subgroup. T' has the further advantage that it can also neatly accommodate the quark masses including a heavy top quark.
