Khovanov homology with mod 2 coefficients
The following Python files were used to produce data for the paper
Twofold quasialternating links, Khovanov homology and instanton homology written with Matt Stoffregen.

kh_mod2.py, reduced Khovanov homology with mod 2 coefficients

kh_twisted.py, Twisted Khovanov homology for a twofold marked link

kh_dotted.py, Dotted diagram homology of a twofold marked diagram
The first file is a basic script that computes the reduced Khovanov homology of a link with mod 2 coefficients. The second and third files are modifications that compute the variants of Khovanov homology that we considered in our paper. In particular, the table at the end of our paper was produced using these files. For an explanation of how to use the code, see:
