It's undoubtedly due to an incomplete and half-way documented implementation. About 1.5 years ago, near the beginning of SAGE, David Kohel (fairly quickly) implemented most of what is in the current quaternion algebra SAGE package. Much has changed in SAGE since then, and I've done work to update the quaternion algebra package a little, as has David. But basically nobody has used it for anything nontrivial *at all* until perhaps a little at the Arizona Winter School a few weeks ago. So the package desparately needs to get used, have all the gaps in functionality exposed, and have them fixed. You are the person to do that. Go for it!! Then send me a patch. Personally, I very much want to implement my modular abelian variety Tamagawa number algorithm in SAGE, and part of this requires a good quaternion algebras package (in order to implement some variant of Pizer's algorithm). So I will be enthusiastic about any improvements to the quaternions package. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@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-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
