Anna, Welcome to the group!
It looks like this code comes from the following ticket: http://trac.sagemath.org/sage_trac/ticket/4470 in which Michael Abshoff comments: commit 10629 is mostly the AUTO code by Bernd Souvignier - the code has been made available under a GPL V2+ compatible license, but that needs to be formalized. It is called via pexpect, but probably can be called via Cython directly. It is only one file. If we keep using the pexpect interface it should be moved into its own spkg. You can see in the file sage/quadratic_forms/quadratic_forms__automorphisms.py (line ~433) ## Call the Souvigner automorphism code souvigner_auto_path = SAGE_ROOT + "/local/bin/Souvigner_AUTO" ## FIX THIS LATER!!! Which echoes the ticket you mentioned. There is no Souvigner_AUTO in local/bin, however. Some quick Googling suggests that this was in sage-3.3.rc0, but I don't know where the source is (this file is just a binary file). His website is here, perhaps someone should contact him: http://www.math.ru.nl/~souvi/ -- Robert L.
