Query: Generalized permutohedra, h-vector of cotransversal matroids and pure
  O-sequences   Stanley has conjectured that the h-vector of a matroid complex is a pure
O-sequence. We will prove this for cotransversal matroids by using generalized
permutohedra. We construct a bijection between lattice points inside a
r-dimensional convex polytope and bases of a rank r transversal matroid.
