Abstract
We consider an family-symmetry model with four generations of leptons and quarks. A mass relation of the form is obtained. The predicted values of individual 4×4 Kobayashi-Maskawa matrix elements are within recent experimental data. If the charged-lepton mass of the fourth generation is at 30 GeV and the -quark mass is at 35 GeV, the masses of the - and -type quarks of the fourth generation are predicted to be 73±2 GeV and 523±3 GeV, respectively, taking account of the renormalization-group effect.
