Thanks for creating it. I've looked through my emails from 2006 and cannot find a trace of the examples I had then. I vaguely remember a certain example which would be getting different answers on different runs when trying to compute Riemann-Roch spaces. William might remember better since his memory is about a million times better than mine. It is also possible that the bug submission form back then was via some sort of web based forum, http://www.singular.uni-kl.de/request_form.html, in which case they might have a copy of the email on their website. > > Cheers, > Martin > > -- > name: Martin Albrecht > _pgp: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8EF0DC99 > _otr: 47F43D1A 5D68C36F 468BAEBA 640E8856 D7951CCF > _www: http://www.informatik.uni-bremen.de/~malb > _jab: martinralbre...@jabber.ccc.de > > > > > > --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
