I tried to set two symbols on top of each other via:
\begin{align*}
\Rightarrow\atop\nLeftarrow
\end{align*}
How can I reduce the space between the symbols? \overset
etc. is what I normally use, but that reduces the size of one of the symbols and I would like them to be of the same size.

Use the
\genfrac
command from the amsmath package.Another possibility is to use an array environment. In this case an optional argument to the
\\
macro allows you to manually adjust the vertical spacing.
