The symmetry properties and the pseudo-orthogonality relations of the super-rotation Clebsh-Gordan coefficients for the tensor product of two irreducible representations of the super-rotation algebra are derived. The symmetric super-rotation 3-j symbol and the symmetric and invariant super-rotation 6-j symbol are defined, their basic properties are described, and their relations to the usual 3-j and 6-j symbols are given.
