The following is a numbered equation in an early chapter of a
thesis<br>
\begin{equation}<br>
\mathrm{\dot{H} + O_2 \rightarrow \dot{O}H + O }<br>
\label{key}<br>
\end{equation}<br><br>
We want to re-use the equation number in a restatement of the <br>
equation many pages on from the first statement because the
reader<br>
may well have forgotten what it referred to ...<br><br>
Is there a better or more elegant solution than this?<br><br>
$$<br>
\mathrm{\dot{H} + O_2 \rightarrow \dot{O}H + O }
\rule{25pt}{0pt} \eqref{key} <br>
