[Python-ideas] Extremely weird itertools.permutations

[Neil Girdhar]

I'm sorry, but I can't find a reference supporting the statement that the
current permutations function is consistent with the mathematical
definition.  Perhaps you would like to find a reference? A quick search
yielded the book "the Combinatorics of Permutations":
http://books.google.ca/books?id=Op-nF-mBR7YC&lpg=PP1   Please look in the
chapter "Permutation of multisets".

Best,

Neil
