This page contains an experimental version of a Sage program that computes the collapsed hat Grid homology of knots in lens spaces with integer coefficients (when the grid number 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), since the program is inefficient and the cell below is hosted on a free server.
