Bianchi.gp
The program Bianchi.gp for the computation of fundamental domains for the Bianchi groups, and the group homology of the latter,
belongs to the PLUME index of the CNRS.
The intensive computations award C3I has been attributed to the thesis developing Bianchi.gp.
This program is based on the specialized computer algebra system Pari/GP; and version 2.4.3 or higher of the latter is required to execute Bianchi.gp.
Pari/GP is available free of charge on the
Pari/GP development headquarters website.
Bianchi.gp is part of the GP scripts library of Pari/GP Development Center.
Bianchi.gp is downloadable from here free of charge, covered by the GNU General Public License 
.
A description of Bianchi.gp is given in the appendix of the PhD thesis of Alexander D. Rahm.
