Dear Professor Cohen, First of all, thank you and Professor Thiery for the replies.
For example, by using the following commands I obtain all meet semi-lattices with 4 elements >P4=[p for p in Posets(4) if p.is_meet_semilattice()] >for p in P4: show(p.plot()) I wonder that the algorithm for doing this in Sage.
