... give a constructive proof of an equivalent restatement of Propo- sition 2.5, by looking at the circular classes of permutations τ ∈ S n which fix n. Note that the statement of Proposition 4.4 ( ... was originally motivated by the algebraic discovery of the formula (A). We now give a bijective proof of (A), which is the special case k = n,  = n−1 of Theorem 3.1, namely m n (i\n;...
