"Similar" Knots (within the Atlas)
Same Alexander/Conway Polynomial: {10_129, K11n39, K11n45, K11n50, K11n132,}
Same Jones Polynomial (up to mirroring, ): {10_129,}
Vassiliev invariants
V2 and V3: | (2, 1) |
V2,1 through V6,9: |

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 0 is the signature of 8 8. Nonzero entries off the critical diagonals (if any exist) are highlighted in red. |
