I currently have the following equation that I would like to write:

```
\begin{equation*}
\pi(X)=\mathbf{N}_4\Bigg\{\left(\begin{matrix} 1
\\2\\1\\3\end{matrix}\right),\left(\begin{matrix}2 & 1 & 2 & 3 \\1 & 2 & 1 &
3\\ 2 & 1 & 3 & 3\\3 & 3 & 3 & 7\end{matrix}\right)\Bigg\}
\end{equation*}
```

But the curly brackets `\Bigg\{`

and `\Bigg\}`

aren't big enough – is there a way to get bigger curly brackets?

## Best Answer

Just use

`\left\{`

and`\right\}`

for the braces as well:
