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 flavor symmetry T ≡ A4, the tetrahedral group, but also by using the alternative flavor symmetry X(24) ≡ SL2(F3) ≡ Q4 × Z3. X(24) does not contain the tetrahedral group as a subgroup, and has the advantage over it as a flavor symmetry that it can not only underwrite bitrimaximal mixing for neutrinos, equally as well, but also provide a first step to understanding the quark mass hierarchy.
