Description: The interlacing number of a set partition.

Let $\pi$ be a set partition of $\{1,\dots,n\}$ with $k$ blocks.  To each block of $\pi$ we add the element $\infty$, which is larger than $n$.  Then, an interlacing of $\pi$ is a pair of blocks $B=(B_1 < \dots < B_b < B_{b+1} = \infty)$ and $C=(C_1 < \dots < C_c < C_{c+1} = \infty)$ together with an index $1\leq i\leq \min(b, c)$, such that $B_i < C_i < B_{i+1} < C_{i+1}$.
