WebApr 3, 2024 · Tait, of course, posed the ménage problem after following a similar line of logic, trying to put an upper bound on the number of knots of each crossing number, but I haven't seen an explicit proof from Tait or Dowker or Thistlethwaite or anyone else that their notation is uniquely decipherable for the prime knots up to chirality.

The Dowker-Thistlethwaite code of a knot diagram is defined as follows. Start following the knot diagram at some regular point. Label the crossings by a number (starting from number 1) in the order in which they are met.
WebHugh Dowker (1978) created another notation based on Tait’s ideas. Morwen Thistlethwaite used Dowker’s notation to create a computer program that generated all prime knots K such that c(K) 13 (1981-82). Jim Hoste, Thistlethwaite, and Jeff Weekes were able to then generate all prime knots K where c(K) 16 (1998). WebSoftware engine implementing the Wolfram Language.
