Given a finite poset P in SAGE. Can one obtain the lattice of antichains or the lattice of order ideals of P as a lattice in SAGE? I just saw how to obtain those things as sets but not as posets.

Thank you very much! This command seems not to be in the manual of SAGE for lattices yet: http://doc.sagemath.org/html/en/refer...
