Description
We investigate the problem of incorporating the fermion generations within the framework of a grand unified SU(N) gauge theory. The requirement of no triangle anomaly and an asymptotically free gauge coupling constant appears to limit the number of light-fermion generations to four. Specializing to an SU(8) model, we exhibit a Higgs mechanism that splits the fermions into heavy and light sets, the latter containing only three generations. We argue that the mass of the heavy generation is in the TeV region
