9-j symbol diagonal as well as even permutations of its rows or columns: An odd permutation of rows or columns yields a phase factor formula_27, where For example: The 9-"j" symbols can be calculated as sums over triple-products of 6-"j" symbols where the summation extends over all admitted by the triangle conditions in the factors: When formula_31 the 9-"j" symbol is proportional to a 6-j symbol: The 9-"j" symbols satisfy this orthogonality relation: The "triangular delta" is equal to 1 when the triad ("j", "j", "j") satisfies the triangle conditions, and zero otherwise. The 6-j symbol is the first representative, , of
