The tetrahedron $A 4$ group has been widely used in studying neutrino mixing matrix. It provides a natural framework of model building for the tri-bimaximal mixing matrix. In this class of models, it is necessary to have two Higgs fields, $\chi$ and $\chi-$, transforming under $A 4$ as 3 with one of them having vacuum expectation values for the thr
