### Abstract

Motivated by dimensional deconstruction, we propose a model of tribimaximal neutrino mixing based on A_{4}×A_{4} symmetry. In this model, the two triplet symmetry-breaking fields of conventional A4 models are taken to transform under different A_{4} group factors, but are not distinguished by any other quantum numbers. An additional bi-triplet flavon field breaks A_{4}×A_{4} to its diagonal subgroup. If the bi-triplet transforms under an additional Z_{3} symmetry, we show that one can construct a general, renormalizable superpotential that yields the desired pattern of symmetry breaking. We identify the features that this model has in common with a deconstructed 5D theory in which A_{4}is a subgroup of a continuous gauged flavor symmetry in the bulk.
