Hi, I've created a poset of permutation elements using the Bruhat partial order:
bruhat_p_order = lambda p,q : p.bruhat_lequal(q) my_poset = Poset([perms, bruhat_p_order]) It seems that when I create the poset, the elements are no longer permutations but "PosetElement"s, and I can't figure out how to "recover" the elements as permutations. I can't even coerce them back to permutations by writing Permutation(my_poset[i]). Specifically, I am creating the poset in order to find all possible total orders of the poset. Once I have the total orders, I'd like to be able to call on the elements again as permutations. Any help is much appreciated!
