Thanks, Anne! That is the problem indeed. Using to_vector(ZZ) resolves it. On Mon, Mar 11, 2013 at 8:50 PM, Anne Schilling wrote: > The problem is that the entries in nl are rational numbers and > not integers: > > sage: type(nl[0]) > sage.rings.rational.Rational > sage: type([0,2,1][0]) > sage.

Hi Daniel! That is an amazing bug. It is treating a literal [0,2,1] differently from a constructed list with the same value. Here is my followup test. (after your stuff) sage: nl = nu.to_vector().list() sage: nl == [0,2,1] True sage: [[None]*s for s in [0,2,1]] [[], [None, None], [None]] sage:

Sorry, I forgot this line when I copied: sage: w=W.an_element() So altogether we would have: sage: from sage.combinat.sf.ns_macdonald import E sage: W=WeylGroup(['A',2]) sage: w=W.an_element() sage: mu=W.domain()([2,1,0]) sage: nu=w.action(mu) sage: nu.to_vector().list() [0, 2, 1] sage: E([0,2,1
