See the full Rolfsen Knot Table. Visit 9 1's page at the Knot Server (KnotPlot driven, includes 3D interactive images!) |
9_1 should perhaps be called "The Nonafoil Knot", following the trefoil knot, the cinquefoil knot and (maybe) the septafoil knot. The next in the series is K11a367. See also T(9,2). |

Vassiliev invariants

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 -8 is the signature of 9 1. Nonzero entries off the critical diagonals (if any exist) are highlighted in red. |
