Trefoil knots with tritangent planes. (English) Zbl 1067.53001
Author’s abstract: As we know, there are examples of trefoil knots without tritangent planes. Here we show that trefoil knots of the familiar shape always have such planes. We relate this result to the search for the minimum number of vertices.
