Abstract The SU(4) Clebsch-Gordan coefficients of the decomposition {N_a } ⊗ {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) ⊃ SU(3)×U(1) ⊃ SU(2)×U(1) ⊃ U(1) using the eigenfunction method along with recurrence relations. Title of program: CGSU4 Catalogue Id: AEBL_v1_0 Nature of problem The SU(4) Clebsch-Gordan coefficients according to the group chain SU(4) ⊃ SU(3) x U(1) ⊃ SU(2) x U(1) ⊃ U(1) are calculated for arbitrary couplings.
