Neutrino Mass Matrix from Delta(27) Symmetry
  The discrete subgroup Delta(27) of SU(3) has some interesting properties which may be useful for understanding charged-lepton and neutrino mass matrices. Assigning leptons to the 3 and 3* representations of Delta(27), a simple form of the Majorana neutrino mass matrix is obtained and compared to present data.
