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.[1] It has the same Alexander polynomial as knot 10132. The cinquefoil knot's Jones polynomial is q−2 + q−4 − q−5 + q−6 − q−7.[2] Its name comes from cinque meaning five, and foil meaning leaf. The double overhand knot is the opened equivalent of the cinquefoil knot.
