The present status of the efforts to develop a closed‐form expression for the product of arbitrary class‐sums in the symmetric group is critically reviewed. The relevant data base is extended by determining the full [(7)] N ·[(1) 1 1 (2) 1 1 …] n product. The extended data base is used to formulate a conjectured recurrence relation for reduced class coefficients of the general form C〈(r 1 + r 2 )A·(r 1 + r 2 + … + r 1 )B〉 in terms of class coefficients in which r 1 and r 2 are eliminated.
