Let $n \in \mathbb{N}$ be a D996: Natural number.
The central binomial coefficient with respect to $n$ is the D996: Natural number
\begin{equation}
\binom{2 n}{n}
= \left| \mathcal{P}_n \{ 1, \ldots, 2 n \} \right|
\end{equation}
Let $n \in \mathbb{N}$ be a D996: Natural number.
The central binomial coefficient with respect to $n$ is the D996: Natural number
\begin{equation}
\binom{2 n}{n}
= \# \left\{ E \subseteq \{ 1, \ldots, 2 n \} : |E| = n \right\}
\end{equation}
