Visit 6 2's page at the Knot Server (KnotPlot driven, includes 3D interactive images!) Visit 6 2's page at Knotilus! Visit 6 2's page at the original Knot Atlas! Dror likes to call 6_2 "The Miller Institute Knot", as it is the logo of the Miller Institute for Basic Research. The bowline knot of practical knot tying deforms to 6_2.

The above data is available with the Mathematica package KnotTheory`, 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.

Khovanov Homology

The coefficients of the monomials $t^{r}q^{j}$ are shown, along with their alternating sums $\chi$ (fixed $j$, alternation over $r$). The squares with yellow highlighting are those on the "critical diagonals", where $j-2r=s+1$ or $j-2r=s-1$, where $s=$-2 is the signature of 6 2. Nonzero entries off the critical diagonals (if any exist) are highlighted in red.
