Vassilliev invariants of knots and their cables @Vivek: it's in section 9.2.2 of "Introduction to Vassiliev Knot Invariants" by Chmutov, Duzhin, and Mostovoy, available at pdmi.ras.ru/~duzhin/papers/cdbook/cdbook.pdf. |

Computer package to compute HOMFLY polynomial? @minimax: see katlas.org/wiki/Cabling for an example. You have to import the program CableComponent.m, and then I believe you want to use CableComponent[BR[TorusKnot[19,3]], Knot[3,1]]. (I haven't used CableComponent before, but this knot seems to at least have the right Alexander polynomial according to the formula $\Delta(t) = \Delta_{T_{3,19}}(t) * \Delta_{T_{2,3}}(t^3)$.) |

Computer package to compute HOMFLY polynomial? The KnotTheory` Mathematica package, available with lots of documentation and examples at katlas.org/wiki/Setup, can compute HOMFLY and many other knot polynomials and even produce cables for you automatically. |
