## Technical Note for Stirling Numbers of the Second Kind

The $\LaTeX$ code for $\ds {n \brace k}$ is \ds {n \brace k} .

The braces around the n \brace k are important.

The \ds is needed to create the symbol in its proper house display style.

Note that while it appears that \ds \set {n \atop k} should do the same job, it is rendered with a subtle difference:

$\ds \set {n \atop k}$

and so is not recommended on $\mathsf{Pr} \infty \mathsf{fWiki}$.
