Cobimaximal neutrino mixing from S3×Z2

It has recently been shown that the phenomenologically successful pattern of cobimaximal neutrino mixing (θ13≠0, θ23=π/4, and δCP=±π/2) may be achieved in the context of the non-Abelian discrete symmetry A4. In this paper, the same goal is achieved with S3×Z2. The residual lepton Z3 triality in the case of A4 is replaced here by Z2×Z2. The associated phenomenology of the scalar sector is discussed
