= Conway-normalized Alexander polynomial

{title2=$\Delta_K(t)=\Delta_K(t^{-1}),\quad\Delta_K(1)=1$}

The symmetric <Alexander polynomial> normalized by the <Conway polynomial> is uniquely fixed for a <knot>. Its sign matters in the <signed Jones evaluation at minus one>, whereas the <knot determinant> retains only the absolute value.
