  We study the effects of considering nontrivial unphysical lepton sector
phases on the group theoretical properties of the flavor and generalized CP
symmetry elements in the case where there are three light, distinct Majorana
neutrino species. We highlight the similarities and differences between the
charged lepton and neutrino sectors and further elucidate the group properties
of the flavor and generalized CP symmetry elements. We show how the inclusion
of these leptonic phases affects the bottom-up constructions of these symmetry
elements and discuss the implications for top-down model building based on
discrete symmetry groups.
