Polygonal Knot

A knot equivalent to a polygon in , also called a tame knot. For a polygonal knot , there exists a plane such that the orthogonal projection  on it satisfies the following conditions:

2. The projections of the vertices of  are not double points of .

Such a projection  is called a regular knot projection.
