It is shown that the universal R matrix in the tensor product of two irreducible representation spaces of the quantum superalgebra U{sub q}{bold (}osp(1{vert_bar}2){bold )} can be expressed by Clebsch{endash}Gordan coefficients. The Racah sum rule satisfied by U{sub q}{bold (}osp(1{vert_bar}2){bold )} Racah coefficients and 6{minus}j symbols is derived from the properties of the universal R matrix in the tensor product of three representation spaces. Considering the tensor product of four irreducible representations, it is shown that Biedenharn{endash}Elliott identity holds for U{sub q}{bold (}osp(1{vert_bar}2){bold )} Racah coefficients and 6{minus}j symbols. A recursion relation for U{sub q}{bold (}osp(1{vert_bar}2){bold )} 6{minus}j symbols is derived from the Biedenharn{endash}Elliott identity. {copyright} {ital 1998 American Institute of Physics.}
