A knot invariant assigns the same value to isotopic <knots>. Examples include the <knot group>, <Alexander polynomial of a knot>, <Seifert genus>, <knot signature> and <Jones polynomial>. Different <knot invariants> can retain different information: isomorphic <knot groups> do not alone imply isotopic <knots>.
