knot (複数形 knots)

3. A maze-like pattern.
   • 1667, John Milton, “Book IV”, in Paradise Lost. […], London: […] [Samuel Simmons], […], →OCLC; republished as Paradise Lost in Ten Books: […], London: Basil Montagu Pickering […], 1873, →OCLC:

     Flowers worthy of paradise, which, not nice art / In beds and curious knots, but nature boon / Poured forth profuse on hill, and dale, and plain.

4. (mathematics) A non-self-intersecting closed curve in (e.g., three-dimensional) space that is an abstraction of a knot (in sense 1 above).

   A knot can be defined as a non-self-intersecting broken line whose endpoints coincide: when such a knot is constrained to lie in a plane, then it is simply a polygon.

       

   A knot in its original sense can be modeled as a mathematical knot (または link) as follows: if the knot is made with a single piece of rope, then abstract the shape of that rope and then extend the working end to merge it with the standing end, yielding a mathematical knot. If the knot is attached to a metal ring, then that metal ring can be modeled as a trivial knot and the pair of knots become a link. If more than one mathematical knot (または link) can be thus obtained, then the simplest one (avoiding detours) is probably the one which one would want.
