Description

The order of the largest clique of the graph.
A clique in a graph

$G$ is a subset

$U \subseteq V(G)$ such that any pair of vertices in

$U$ are adjacent. I.e. the subgraph induced by

$U$ is a complete graph.

Map

incomparability graph

Description

The incomparability graph of a poset.

Map

to poset

Description

Return the poset obtained by interpreting the tree as the Hasse diagram of a graph.
