What I want to do is to place a letter on top of another. Specifically because I want to be able to write a specific representation of Greek numerals with large numbers.
I just need to be able to put any Greek letter above a Mu or just M in the Greek alphabet.
I also want to write some symbols smaller than others. How do I do that?
Something like this??
\documentclass{article}
\usepackage{stackengine}
\stackMath
\renewcommand\stacktype{L}
\setstackgap{L}{.8\baselineskip}
\newcommand\greekstack[2]{\stackon{#1}{\scriptscriptstyle#2}}
\begin{document}
\greekstack{\alpha}{1}
\greekstack{\lambda}{30}
\greekstack{\rho}{100}
\bigskip
\greekstack{\mu}{\gamma}
\greekstack{M}{\delta}
\end{document}
Something like this?
\def\greekstack#1#2{\leavevmode
\vbox{\offinterlineskip\halign{\hss$##$\hss\cr\scriptstyle#2\cr\mathstrut#1\cr}}}
\greekstack{\alpha}{1}
\greekstack{\lambda}{30}
\greekstack{\rho}{100}
\medskip
\greekstack{\mu}{\gamma}
\greekstack{M}{\delta}
\bye
