Bianchi.gp
The program Bianchi.gp belongs to the PLUME index of the CNRS.
Bianchi.gp computes a fundamental domain for the Bianchi groups in hyperbolic 3-space,
the associated quotient space and essential information about the group homology
and equivariant K-homology of the Bianchi groups.
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.
