This page contains an experimental version of a program that computes the collapsed hat Grid homology of links in lens spaces with integer coefficients (when the grid number $n$ is < 5).

A sample session should start automatically; you can then input the parameters (grid number and the two positive coprime integers determining the lens space) and press the "Update" button.
Note that it might take a long time if you choose knots with big parameters (i.e. $n >3$). You can find here the instructions for this program.
If something does not work, or if you have any comment please let me know at celoria

I just realized that the decategorifications have the wrong sign! going to fix it ASAP.

Added links! And shortly it should work for $S^3$ too.
