Note that a partition and its conjugate give the same degree representation of the symmetric group. We take the lexicographically earlier of the two.

If p_1 >= p_2 >= ... >= p_k is the partition of n, the degree of the representation (given in A003040) is n! * Product_{i<j} (b_i - b_j) / Product_i (b_i!), where b_i = p_i+k-i.
