Let s, t, m, n be positive integers such that sm = tn. Define N (s, t; m, n) to be the number of m Γ— n matrices with entries from {0, 1}, such that each row sum is s and each column sum is t. Equivalently, N(s, t; m, n) is the number of labelled semiregular bipartite graphs, where one colour class c
