This partially ordered set is always a distributive lattice.
The rational numbers with the ordinary ordering are a densely ordered set in this sense, as are the real numbers.
If every element of a partially ordered set is either a minimal element or a maximal element, then the corresponding comparability graph is bipartite.

If a partially ordered set has one minimal element, has one maximal element, and has an upward planar drawing, then it must necessarily form a lattice, a set in which every pair of elements has a unique greatest lower bound and a unique least upper bound.

Like every partially ordered set, Open(X) forms a small category by adding a single arrow U→ V if and only if U⊆ V{\displaystyle U\subseteq V.
For instance, Dilworth's theorem states that the minimum number of chains in a partition of a partially ordered set into chains equals the maximum size of an antichain, and can be rephrased as stating that the complements of comparability graphs are perfect.
Part programme": an ordered set of instructions in a language and in a format required to cause operations to be effected under automatic control, which is either written in the form of a machine"programme" on an input medium or prepared as input data for processing in a computer to obtain a machine"programme" reference:"ISO" 2806-1980.
Using this coloring interpretation, together with a separate proof of Dilworth's theorem for finite partially ordered sets, it is possible to prove that an infinite partially ordered set has finite width w if and only if it has a partition into w chains.

Mirsky's theorem characterizing the height of a partially ordered set in terms of partitions into antichains can be formulated as the perfection of the comparability graph of the partially ordered set, and Dilworth's theorem characterizing the width of a partially ordered set in terms of partitions into chains can be formulated as the perfection of the complements of these graphs.
