Swiss Knots 2011

Knot Theory and Algebra

Lake Thun, May 23-27


The Swiss Link represents every Swiss canton, respecting the touching relations. It is an alternating 3-component 25-crossing link (3 of the crossings are nugatory). It is too big to be on the Knot Atlas, yet its three 2-component sublinks are as follows:

  • The mirror of L11a198, which in itself has one unknot component, and one component which is a mirror 31.
  • Hopf link connect sum that same mirror 31.
  • A Hopf link.

For the details, see the mathematica notebook SwissKnots2009.

The Swiss Link was drawn by Sebastian Baader for Swiss Knots 2009. The xfig source is here.
