Description

The ground state for type A2n(2)+ should be based on \Lambda_n rather than \Lambda_0 due to the equivalence with type A2n(2). Since this is based on \Lambda_0, we have:

sage: K = crystals.KirillovReshetikhin(CartanType(['A',6,2]).dual(), 1,1)
sage: T = tensor([K,K,K])
sage: hw = [x for x in T if x.is_highest_weight([1,2,3])]
sage: for elt in hw:
....:     elt.energy_function()
....:     elt.energy_function('definition')
....:     print ""

Looks good! For A_{2n}{(2)} dual there was indeed a bug in the path to the ground state beforehand.
