10 86

Warning. There is a mixup in the original (1976) Rolfsen table between the pictures and the invariants of the knots 10_83 and 10_86. That mixup lead to a similar mixup here. In the new (2003) edition of Rolfsen's book the mixup was corrected and on August 17, 2004, it was corrected here (actually in Dror's original Knot Atlas) consistently with Rolfsen's correction. In the years between 1976 and 2003 other authors fixed the problem in different ways and our enumeration here may be different than theirs. Dror would like to thank Z-X. Tao for telling him about the (now corrected) mixup here and A. Stoimenow for telling him about the mixup in Rolfsen's original table.

Your input (in red) is realistic; all else should have the same content as in a real mathematica session, but with different formatting.

Khovanov Homology

The coefficients of the monomials $t^rq^j$ 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 $s=$ 0 is the signature of 10 86. Nonzero entries off the critical diagonals (if any exist) are highlighted in red.
