Abstract. Some properties of the generating functions and their application to the construction of the integrity basis for the group decomposition Gi ⊃ Gi+1 are considered. Some of these functions, which are needed for the construction of the basic vectors and the Hamiltonian in the rotational limit of IVBM U(6) ⊃ U(3)×U(2) ⊃ SO(3), are obtained in an explicit form.
