Signature


\begin{params}
{\em a} & M & A matrix\\
\end{params}

\begin{retval}
Returns $(det?, d)$\ such that $d$\ is always a factor of
the de...
...s exactly the determinant of $a$if $det?$\ is {\it true}\xspace .
\end{retval}

\begin{remarks}
$d$\ can also happen to be the determinant of $a$\ when $det?$\ is
{\it false}\xspace , but the algorithm was unable to prove it.
