WebNov 9, 2024 · 7. I understand that, in 1914, Dehn proved that the trefoil knot is chiral (it doesn't equal its mirror image). However, the paper in which he does so is in German, and I can't find a description of his proof anywhere else. The only proof I know of its chirality is through the Jones polynomial/Kauffman bracket or something stronger, but those ... WebMar 4, 1997 · A trefoil is the simplest knot with irreducible negative or positive nodes (Fig. 1d), and therefore any bias favoring the formation of nodes of a particular sign may in turn favor the formation of one chiral trefoil over the other.
