How to put a letter above another?

Question

How do I "stack" a letter above (not in front) another (in math mode)? It should look the same as binomial coefficients, just without the parentheses (which rules out \stackrel and \overset, since it makes the symbol on top smaller, as if it's tweaked superscript).

You can make one such command using \genfrac:

\makeatletter
\newcommand{\stackover}{\genfrac{.}{.}\z@{}}
\makeatother

Then use it like:

\[\stackover{a}{b}\]

It's not working. Do I need some packages for this? – Lazar Ljubenović Dec 22 '13 at 17:56
@LazarLjubenović: You need amsmath – Francis Dec 22 '13 at 17:57
Yes, I'm using it, but it's still not working. As if it doesn't recognize that I've created a new command. – Lazar Ljubenović Dec 22 '13 at 17:58
