Description

The independence gap of a graph.
This is the difference between the independence number St000093The cardinality of a maximal independent set of vertices of a graph. and the minimal size of a maximally independent set of a graph.
In particular, this statistic is $0$ for well covered graphs

Map

cone

Description

The cone of a graph.
The cone of a graph is obtained by joining a new vertex to all the vertices of the graph. The added vertex is called a universal vertex or a dominating vertex.

clique graph

Description

The clique graph of a graph.
The clique graph of a graph $G$ has as vertex set the set of maximal cliques $G$ and an edge between vertices corresponding to cliques that intersect.
In other words, it is the intersection graph of the maximal cliques of $G$.
