Abstract
A double rotor vector coherent state construction of the SU(4) 3 SU(2) x Sup) Wigner supermultiplet leads to a simple matrix representation of this scheme. Matrix elements of the vector coherent state realizations of the group generators are given by very simple expressions in tem of ordinary spin (S) and isospin (T) Wigner coefficients with intrinsic projection labels KS and Kg. The K-mawix technique is used to effectively elevate these labels lo the status of good quantum numbers. The KKt matrices Bre given in analytic form for a number of impomt irreducible representations.
