But I believe the heavier This would be great to have in sage. I wanted to work on something like this in collaboration with Andrew Sutherland a few months back, but that whole annoying thesis thing got in the way. Our idea was to have the underlying abstract group algorithms (like computing discrete logs, exponents of groups, orders of groups, group structures etc) written in C++ with templates. Andrew has had a lot of experience with this. One instantiation would be a black box using C function pointers, which we could then plug into a cython class to perform the arithmetic. david --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
