Pretzel link

The (−2,3,7) pretzel knot has two right-handed twists in its first tangle, three left-handed twists in its second, and seven left-handed twists in its third.

In knot theory, a branch of mathematics, a pretzel link is a special kind of link. A pretzel link which is also a knot (i.e. a link with one component) is a pretzel knot.

In the standard projection of the $(p_1,\,p_2,\dots,\,p_n)$ pretzel link, there are $p_1$ left-handed crossings in the first tangle, $p_2$ in the second, and, in general, $p_n$ in the nth.
