Again, I don't know what OmegaPoly is but my guess is that it's not defined when n=0. For example, for n in (0..6): print(ib(2, n).list()) doesn't work because the cyclotomic_poly isn't defined at n=0. Are you saying, the error message it spits out, AttributeError: 'int' object has no attribute 'list', is misleading? I guess I'm being dense this morning but I don't understand why you think there is something wrong with the sum command. -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to sage-support+unsubscr...@googlegroups.com. > To post to this group, send email to sage-support@googlegroups.com. > Visit this group at https://groups.google.com/group/sage-support. > To view this discussion on the web visit > https://groups.google.com/d/msgid/sage-support/4fc00a73-06c5-42be-9d5b-73bc53fcc683%40googlegroups.com > <https://groups.google.com/d/msgid/sage-support/4fc00a73-06c5-42be-9d5b-73bc53fcc683%40googlegroups.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
