Hi Bruce, You can also do
sage: C = KirillovReshetikhinCrystal(['A',1,1],1,2) sage: B = C.classical_decomposition() sage: L = CombinatorialFreeModule(ZZ,B.weight_lattice_realization()) sage: T = TensorProductOfCrystals(*[C]*3) sage: hw = [a for a in T if a.is_highest_weight(index_set=[1])] sage: sum( L.term( sum(a.lift().weight() for a in b), 1 ) for b in hw ) B[(3, 3)] + 3*B[(4, 2)] + 2*B[(5, 1)] + B[(6, 0)] Then you can still compute the energy function in T.
