# Definition:Stirling Numbers of the Second Kind/Technical Note

## Technical Note for Stirling Numbers of the Second Kind

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

The braces around the n \brace k are important.

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

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

$\displaystyle \left\{ {n \atop k} \right\}$

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