**Abstract:
**There is a method of finding the group presentation
of a tame knot. However, it is not an easy task to distinguish groups given
their presentations, even in particular examples. Therefore, one needs to find
presentation invariants. We shall first consider the Alexander matrix and
elementary ideals of a given finite presentation in a general setup then
restrict our attention to knot groups and get knot polynomials which happen to
be knot invariants of trivial distinguishability.
