Stirling numbers are a part of combinatorial mathematics and come in two main types: the Stirling numbers of the first kind and the Stirling numbers of the second kind. 1. **Stirling Numbers of the First Kind**: Denoted by \\( c(n, k) \\), these numbers count the number of permutations of \\( n \\) elements with exactly \\( k \\) disjoint cycles.
