Definition:Edgeless Graph

Definition
An edgeless graph is a graph with no edges.

That is, an edgeless graph is a graph of size zero.

Equivalently, an edgeless graph is a graph whose vertices are all isolated.

The edgeless graph of order $n$ is denoted $N_n$ and can be referred to as the $n$-edgeless graph.
