Resumen:
For any finite group G, we construct a finite poset (or equivalently, a finite T0-space) X,whose group of automorphisms is isomorphic to G. If the order of the group is n and it has rgenerators, X has n(r+2) points. This construction improves previous results by G. Birkhoffand M.C. Thornton. The relationship between automorphisms and homotopy types is alsoanalyzed.
