Warning. In 1974 K. Perko noticed that the knots labeled 10_161 and 10_162 in Rolfsen's tables are in fact the same. In our table we removed his 10162 and renumbered the subsequent knots, so that our 10 crossings total is 165, one less than Rolfsen's 166. Read more: [1] [2] [3] [4].

[edit] Khovanov Homology

The coefficients of the monomials trqj are shown, along with their alternating sums χ (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 = -4 is the signature of 10 161. Nonzero entries off the critical diagonals (if any exist) are highlighted in red.
