, as shown in the (simulated) Mathematica session below. Your input (in red) is realistic; all else should have the same content as in a real mathematica session, but with different formatting. This Mathematica session is also available (albeit only for the knot 5_2) as the notebook PolynomialInvariantsSession.nb.

Vassiliev invariants
V2 and V3: | (Data:Hoste-Thistlethwaite Knot Page/V 2, Data:Hoste-Thistlethwaite Knot Page/V 3) |
V2,1 through V6,9 were provided by Petr Dunin-Barkowski <barkovs@itep.ru>, Andrey Smirnov <asmirnov@itep.ru>, and Alexei Sleptsov <sleptsov@itep.ru> and uploaded on October 2010 by User:Drorbn. Note that they are normalized differently than V2 and V3.
Khovanov Homology
The coefficients of the monomials are shown, along with their alternating sums (fixed , alternation over ). The squares with yellow highlighting are those on the "critical diagonals", where or , where Data:Hoste-Thistlethwaite Knot Page/Signature is the signature of Hoste-Thistlethwaite Knot Page. Nonzero entries off the critical diagonals (if any exist) are highlighted in red. | Data:Hoste-Thistlethwaite Knot Page/KhovanovTable |
