khoca computes Khovanov-Rozansky sl(n) homologies of so-called ”bipartite” knots and links. It also computes Khovanov sl(2) homology of all knots and links. It supports: Homology over the integers, the rationals or a prime field. Either equivariant homology, or homology with an arbitrary fixed potential. All pages of the spectral sequence of filtered homology over a field. Reduced and unreduced homology. Homology of sums and mirror images of knots.
