  We present analyses of the sixty hybrid textures of neutrino mass matrix,
which have an equality of matrix elements and one zero. These textures are
possibly derived in the models with discrete flavor symmetry. Only six textures
among sixty ones are excluded by the present experimental data. Since there are
many textures which give similar predictions, the textures are classified based
on the numerical results. The neutrinoless double beta decay is also examined
in these textures. Our results suggest that there remain still rich structures
of the neutrino mass matrix in the phenomenological point of view.
