Abstract
We discuss the lepton flavor violating decays of a tau lepton into three lighter ones charged leptons in the presence of heavy Majorana neutrinos. Updated predictions obeying the current limits of the heavy-light mixing angles are presented. We point out the differences between the case of two non-degenerate and degenerate heavy Majorana neutrinos. In the latter, the two heavy states reduce to a single Dirac neutrino, where the lepton number violating effects vanish.
