Link

Formally, a link is one or more disjointly embedded Circles in 3-space. More informally, a link is an assembly of Knots with mutual entanglements. Kuperberg (1994) has shown that a nontrivial Knot or link in $\Bbb{R}^3$ has four Collinear points (Eppstein). Doll and Hoste (1991) list Polynomials for oriented links of nine or fewer crossings. A listing of the first few simple links follows, arranged by Crossing Number.
