= Stirling numbers of the first kind
{wiki=Stirling_numbers_of_the_first_kind}

Stirling numbers of the first kind, denoted by \\(c(n, k)\\), count the number of ways to express a permutation of \\(n\\) elements as a product of \\(k\\) disjoint cycles. In other words, they are used in combinatorial mathematics to determine how many different ways a set can be partitioned into cycles.
