Program for calculating SU(4) Clebsch-Gordan coefficients
The SU(4) Clebsch-Gordan coefficients of the decomposition {N-a} circle times {N-b} -> {N} are calculated for arbitrary irreducible representations {N-a}, {N-b} and {N}. They are efficiently computed for the group chain SU(4) superset of SU(3)xU(1) superset of SU(2)xU(1) superset of U(1) Using the eigenfunction method along with recurrence relations.
