Abstract

We describe a fit to the charged fermion mass hierarchy using the chiral quantum numbers of the maximal anti-grand unification group SMG3 × U(1)f, where SMG SU(3) × SU(2) × U(1). This fit suggests a set of Higgs fields responsible for the breakdown, near the Planck scale, of SMG3 × U(1)f to the Standard Model group.
