Abstract
Let π be a permutation in Sn, the symmetric group on n letters. Let k be an integer, 2 ⩽ k ⩽ n, and suppose that π can be represented as a product of k-cycles. Denote by fk(π) the minimal number of k-cycles required for such a representation. In this paper bounds for fk(π) are derived. These bounds are used to determine \(\mathop {\lim }\limits_{n \to \infty }\) for all k, where fk(n)=max{fk(π) | π ε Sn}.
