Lepton mixing predictions from Δ(6n2) family symmetry

We obtain predictions of lepton mixing parameters for direct models based on Delta(6n(2)) family symmetry groups for arbitrarily large n in which the full Klein symmetry is identified as a subgroup of the family symmetry. After reviewing and developing the group theory associated with Delta(6n(2)), we find many new candidates for large n able to yield reactor angle predictions within 3 sigma of recent global fits. We show that such Delta(6n(2)) models with Majorana neutrinos predict trimaximal mixing with reactor angle theta(13) fixed up to a discrete choice, an oscillation phase of either zero or pi and the atmospheric angle sum rules theta(23) = 45 degrees -/+ theta(13)/root 2, respectively, which are consistent with recent global fits and will be tested in the near future.
