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() [[1, 2, 2], [1, 2, 3], [1, 3, 2]] sage: Necklaces([0,2,1]).cardinality() 1 I think that while the second answer is correct, the first one should return [[2, 3, 3]]. The only problem that I can see is that code seems to not be written to handle input vectors that have 0 entries. The documentation needs to be modernized a bit. -Mike -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
