Commutative Schur rings over symmetric groups II: The case n = 6

We determine the commutative Schur rings over S6 that contain the sum of all the transpositions in S6.There are eight such types (up to conjugacy), of which four have the set of all the transpositions as a principal set of the Schur ring.
