I was double checking a problem from my combinatorics class (we are doing
Pólya enumeration) and I came across what I think is a bug in the
necklaces.py code.
I'll open a ticket, but I want to double check in case someone knows more
about this code than I do.
sage: Necklaces([0,2,1]).list()
Hey Mike,
We had the problem for Lyndon words
(http://trac.sagemath.org/ticket/12997), but it was hacked around. So
either we fix _sfc/_simple_fixed_content or we hack around it by stripping
leading 0's and then modifying the yielded elements (by adding # leading
0's).
Best,
Travis

That is really good to know. It seems that the code isn't handling input
vectors with leading 0's.
