Inthe supersymmetric seesaw model of neutrino masses, augmented by thenon-Abelian discrete tetrahedral symmetry A₄, a specific pattern of neutrinomixing is automatically generated if one of the three heavysinglet neutrino superfields acquires a nonzero vacuum expectation value. Thispattern turns out to be exactly that of tribimaximal mixing,i.e. sin²theta₂₃=1/2, sin²theta₁₂=1/3, and sin²theta₁₃=0, in good agreement with data.
