I have no idea if the following is related, but thought I'd post it here rather than support in case it is:
---------------------------------------------------------------------- | Sage Version 3.3.alpha5, Release Date: 2009-02-03 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- sage: f(n)=n^2+n+41 sage: f(39),is_prime(f(39)),factor(f(39)) (1601, True, 1601) sage: f(40),is_prime(f(40)),factor(f(40)) (1681, False, 1681) sage: factor(1681) 41^2 I think I would consider this a bug; even if I shouldn't put a symbolic thing in factor, it should give an error rather than refuse to factor. - kcrisman --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
