Abstract
Matrix elements of the unit tensor operators of ranks (1), (2) and (1,1) in the non-orthonormal Draayer basis of SU(4) are found. The evaluation algorithms for the SU(4) coupling coefficients are proposed for coupling one arbitrary and one four-, six- or ten-dimensional irreducible representation of SU(4) in the SU(2)*SU(2) chain, as well as in the case of the semistretched coupling. The construction of the overlaps of the Draayer basis states is considered.
