Pretzel link
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, p, …, p) pretzel link, there are p left-handed crossings in the first tangle, p in the second, and, in general, p in the nth.
A pretzel link can also be described as a Montesinos link with integer tangles.
