We present numerical and comprehensive analyses of the sixty hybrid texturesof neutrinos, which have an equality of matrix elements and one zero. Thesetextures are possibly derived from the discrete symmetry. Only six texturesamong sixty ones are excluded by the present experimental data. Since there aremany textures which give similar predictions, the textures are classified basedon the numerical results. The neutrinoless double beta decay is also examinedin these textures. Our results suggest that there remain still rich structuresof the neutrino mass matrix in the phenomenological point of view.Comment: 19 pages, 9 figures; analytical discussions added, table and reference adde
