# Restate Theorem with given theorem setup

I am given the follwoing theorem setup, which I have to use.

\numberwithin{equation}{chapter}
\newtheorem{theorem}{Theorem}[chapter]
\newtheorem{definition}[theorem]{Definition}
\newtheorem{proposition}[theorem]{Proposition}
\theoremstyle{nonumberplain}
\theorembodyfont{\normalfont}
\theoremsymbol{\ensuremath{\square}}
\newtheorem{proof}{Proof}


How is it possible to restate a theorem with the same number as when stated first. I don't mind if I have to rewrite the theorem or even put the number in by hand, because I only need it once.

• I tried several option from this question already. But none seemed to work. – MatheMarco Feb 19 at 12:34
• Then I propose you provide a complete and minimal document (from \documentclass to \end{document}) with an example of what have you tested and doesn't work. – Ignasi Feb 19 at 12:43

I solved my problem by changing the setup a bit.

\numberwithin{equation}{chapter}
\newtheorem{theorem}{Theorem}[chapter]
\newtheorem{definition}[theorem]{Definition}
\newtheorem{proposition}[theorem]{Proposition}
\newtheorem*{thm345}{Theorem 3.45}
\theoremstyle{nonumberplain}
\theorembodyfont{\normalfont}
\theoremsymbol{\ensuremath{\square}}
\newtheorem{proof}{Proof}


Now using:

\begin{thm345}
theorem text
\end{thm345}


gives me what I want
