This category contains examples of Stirling Numbers of the Second Kind.

Stirling numbers of the second kind are defined recursively by:

$\ds {n \brace k} := \begin{cases}

\delta_{n k} & : k = 0 \text{ or } n = 0 \\ & \\ \ds {n - 1 \brace k - 1} + k {n - 1 \brace k} & : \text{otherwise} \\ \end{cases}$
