I have an equation with an intersection which has multiple limit levels, like this,

\[
\langle H, H'\rangle = \bigcap_{\substack{
L \leq G, \\
H \cup H' \subseteq L.
}}L
\]

enter image description here

It compiles nicely, but that code prints L and the equal sign too far apart from the intersection. Is there a way to eliminate those spaces in order to make the equation look better?

mathtools provides the macro \mathclap (and also \crampedclap, \smashoperator) for precisely this occasion (see pages 4–7 of the manual):

\usepackage{mathtools}
%...
\begin{equation*}
  \langle H, H'\rangle = \bigcap_{\mathclap{\substack{
  L \leq G, \\
  H \cup H' \subseteq L.
  }}}L
\end{equation*}

Try \usepackage{mathtools} and

\[
\langle H, H'\rangle = \smashoperator{\bigcap_{\substack{
L \leq G, \\
H \cup H' \subseteq L.
}}}L
\]
