I think pari/gp can do arithmetic over general Galois fields. I certainly have a recollection of doing that with it in the past. Its free (GPL) too, and has a library that could be wrapped with SWIG/etc to make it python friendly. http://pari.math.u-bordeaux.fr/ * PARI is a C library, allowing fast computations. * gp is an interactive shell giving access to PARI functions, much easier to use. * GP is the name of gp' s scripting language * gp2c the GP-to-C compiler makes the best of both worlds If someone did wrap PARI in python it would certainly be easier to use than GP which I found very unintuitive! In fact I just found this which looks like just the job! http://www.fermigier.com/fermigier/PariPython/readme.html -- Nick Craig-Wood <[EMAIL PROTECTED]> -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list
