A Hasse diagram is a directed graph that encodes a finite poset (P, ≤). It consists of a vertex for each element of P, with a directed edge (usually oriented upwards) from a ∈ P to b ∈ P …

If (S, ) is a partially ordered set, we can represent this group in a schematic format called (Hasse diagram), where S is a finite set, as follows: We represent each element of S in a small circle …

Hasse diagrams of isomorphic posets Not a Hasse diagram here Ci is a chain. Let A be any antichain. Since #(Ci ∩ A) ≤ , we ave k ≥ #A hat P i
