 ##  <Description>
 ##  returns a new random mutable <A>m</A><M>\times</M><A>m</A> matrix with integer
 ##  entries that is invertible over the integers.
 ##  Optionally, a random source <A>rs</A> can be supplied.
-##  If the option <A>domain</A> is given, random selection is made from <A>domain</A>, otherwise
+##  If the option <A>domain</A> is given, random selection is made from
