FINITE NONABELIAN SUBGROUPS OF SU(N) WITH ANALYTIC EXPRESSIONS FOR THE IRREDUCIBLE REPRESENTATIONS AND THE CLEBSCH-GORDAN-COEFFICIENTS

We present two sequences of finite nonabelian groups which are semidirect products of three Zn groups. Although these groups are not simply reducible (in the tensor product of two irreducible representations an irreducible representation is obtained more than once) we give analytic expressions for the irreducible representations and the Clebsch-Gordan coefficients. © 1980 American Institute of Physics.
