摘要：
The peculiar fermion mass and mixing patterns, especially the observed mass hierarchies among charged fermions and the striking differences between lepton and quark mixings, suggest the existence of symmetries acting on generation space. I briefly review Grand Unified models incorporating such a symmetry and elucidate particular features of this type of models by presenting a supersymmetric SU(5) x S-4 model.
