Let L be a finite distributive lattice. Is it possible to calculate the automorphism group G of L via SAGE? Can one display all the elements of G and their orders?

Like this

sage: P = posets.PentagonPoset()
sage: P.hasse_diagram().automorphism_group()
Permutation Group with generators [()]
sage: P = posets.DiamondPoset(6)
sage: P.hasse_diagram().automorphism_group()
Permutation Group with generators [(3,4), (2,3), (1,2)]
