An important class of flavour groups that are subgroups of U (3) and that predict experimentally viable lepton mixing parameters including Majorana phases, is the Δ(6 n 2 ) series. The most well-known member is Δ(24) = S 4 . I present results of several extensive studies of lepton mixing predictions obtained in models with a Δ(6 n 2 ) flavour group that preserve either the full Klein symmetry or a Z 2 subgroup for neutrinos and can include a generalised CP symmetry. Predictions include mixing angles and the Dirac CP phase generally; and if invariance under a generalised CP symmetry is included, also Majorana phases. For this, the interplay of flavour group and generalised CP symmetry has to be studied carefully.
