| Mar 9, 2023 at 1:53 | comment | added | Sam Hopkins | There was recent progress on Fox's conjecture: arxiv.org/abs/2303.04733. (This paper is sort of along the lines of what I suggested in the previous comment - using a version of the Tutte polynomial for a certain kind of graphical representation of the knot, and then applying the powerful machinery of Lorentzian polynomials.) | |
| Jul 9, 2022 at 20:49 | comment | added | Sam Hopkins | Is it possible to rephrase this conjecture as about coefficients of Tutte polynomials of graphs? | |

The knot must be alternating.

| Nov 12, 2009 at 4:12 | comment | added | Ryan Budney | There's definately a lot of non-alternating counter-examples to this conjecture in the knot tables. | |
| Nov 12, 2009 at 4:09 | comment | added | Autumn Kent | I think the knot has to be alternating. | |
