|Knot Theory Calculators|
Here is a list of web pages that offer online computation of knot invariants that are not readily listed in a table. We have opened this page in a second window, since the use of some of the calculators might call upon cutting and pasting information (such as Seifert matrices) from the knot table into the calculator.
Concordance Calculator:  Finds concordance relations between knots of 9 or fewer crossings.
This is not working! Homology Calculator:  Computes the homology of a cyclic branched cover of S^3 branched over a knot, given a Seifert matrix for the knot.
