I think the problem is just one of documentation. In fact, the twist_values command calls into lcalc, and it's giving you twists by quadratic characters with *conductor* between dmin and dmax, *not* the characters of the form (d/.) with d between dmin and dmax. As it happens, the Kronecker symbol (3/.) happens to have conductor 12, not 3, which is what's causing the confusion: sage: kronecker_character(3).conductor() 12 Then this should be the value you want: sage: lcalc.twist_values(2,12,12) [(12, 0.949703126)] I'll file a trac ticket about this right now ... and a patch is up: http://trac.sagemath.org/sage_trac/ticket/5896 Anyone want to give this a quick review? -cc --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
