Assuming that the electroweak group is the Glashow-Weinberg-Salam model, it is proved that the smallest Pati-Salam--type grand-unification groups are SU/sub L/(8)xSU/sub R/(8) with a single coupling constant or SU(4)xSU/sub L/(2)xSU/sub R/(2) with two coupling constants. The color group must be SU(3) with quarks in color triplets. The smallest groups in the Pati-Salam--type models which are capable of unifying three families in the same multiplet, are SU/sub L/(24)xSU/sub R/(24) with a single coupling constant and SU(4)xSp/sub L/(6)xSp/sub R/(6) with two coupling constants.
