Pisano and Pleitez have introduced an interesting SU(3${)}_{\mathit{C}}$ \ensuremath{\bigotimes} SU(3${)}_{\mathit{L}}$ \ensuremath{\bigotimes} U(1${)}_{\mathit{N}}$ gauge model which has the property that gauge anomaly cancellation requires the number of generations to be a multiple of 3. We consider generalizing that model to incorporate right-handed neutrinos. We find that there exists a nontrivial generalization …
