A 6-pq and a 9-pq symbol are defined and given in simplified expressions. Symmetry properties, orthogonality relations and sum rules for the 6-pq and 9-pq symbols are given with phase factors and degeneracy labels specified. Two expressions for theSU3 crossing matrix in terms of a 6-pq and a special 9-pq symbol are given; the latter is preferred for examining the symmetry properties of theSU3 crossing matrix. Three useful equalities are derived, one of which was stated by de Swart without proof.
