Description
The Grundy value of the game of creating an independent set in a graph.
Two players alternately add a vertex to an initially empty set, which is not adjacent to any of the vertices it already contains.
Alternatively, the game can be described as starting with a graph, the players remove vertices together with their neighbors, until the graph is empty.

line graph
Description
The line graph of a graph.
Let $G$ be a graph with edge set $E$. Then its line graph is the graph with vertex set $E$, such that two vertices $e$ and $f$ are adjacent if and only if they are incident to a common vertex in $G$.

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.
