Intersection on a range
Like this?
\begin{displaymath}
\bigcap\limits^n_{i=0}
\end{displaymath}
If you want to use it as inline math you could write it like this:
$\bigcap^n_{i=0}$
Since it's a very large symbol I wouln't suggest the inline solution
Here is a solution creating the output you described
{\bigcap}_{i=0}^k
