What I understand from that sentence in the documentation is that if the starting set and ending set share some vertex, you may get cycles in the output, and each cycles will have the same point at its beginning as at its end - specifically, a point which is in both the starting set and the ending set.
However, this doesn't explain how [1,2,3,2] is a path in which no vertex appears twice. It looks to me like 2 quite clearly appears twice. Looks like a bug. -Keshav ---- Join us in #sagemath on irc.freenode.net ! -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
