I want to have my theorem environments to enumerate using both numbers and letters. Right now I have this:
\documentclass{article}
\usepackage{amsthm}
\newtheorem{theorem}{Theorem}[section]
\begin{document}
\setcounter{section}{1}
\begin{theorem}
This enumerates as ``1.1." but I want ``1.1.a."
\end{theorem}
\begin{theorem}
Then this one would be ``1.1.b"
\end{theorem}
\end{document}
I know I can use
\renewcommand*{\thetheorem}{\alph{theorem}}
to enumerate with letters but I'm not sure how to proceed in applying that to this situation.

refer to what?\newtheorem{theorem}{Theorem}[subsection]
I can get 1.1.1, but how would I get the lettering?
