I am trying to construct the fee module on the set of instances of a class G. I start with
M = CombinatorialFreeModule(QQ,G) If f,g are instances of G I then continue with a = M.monomial(f) b = M.monomial(g) and I can then form a+a , a+b etc. and a - a is indeed 0. However if I try 2*a I get a TypeError If I try M = CombinatorialFreeModule(QQ,NonNegativeIntegers()) a = M.monomial(3) then 2*a seems to work fine. Can anyone tell me what I am doing wrong and/or explain this? Thanks -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
