The Cinquefoil knot, also known as Solomon's Seal knot, and 51 in most tables, is a (5,2)-torus knot with five crossings. Its writhe is 5, it is invertible, but not amphichiral. It has the same Alexander polynomial as knot 10132. It's Jones polynomial is q−2 + q−4−q−5 + q−6−q−7. Its name comes from cinque meaning five, and foil meaning leaf.
