List of possible invairants to implement:

Alexander Polynomial Conway Polynomial Jones Polynomial HOMFLY-PT Polynomial Kauffman 2-variable Polynomial (F polynomial) Writhe Linking Number Seifert Genus (Upper Bound) Turaev Genus (more advanced but diagrammatic) Tricolorability n-Colorability (mod n coloring)

Modules

affine_index_polynomial(k[, variable])
arrow_polynomial(k[, variable, normalize])
bracket	The bracket polynomial <.> (aka the Kauffman bracket) is a polynomial invariant of unoriented framed links.
cache
homflypt	l * P(L+) + l^-1 * P(L-) + m * P(L0) = 0

module	R-module
tests
unplugging(k)	Computes the "unplugging" invariant T.
writhe(k)	The writhe is the total number of positive crossings minus the total number of negative crossings.
