More precisely, let G be a graph with n vertices.
The cycle graph with n vertices is called Cn.
The degree sum formula implies that every r-regular graph with n vertices has nr/2 edges.
Every 1-planar graph with n vertices has at most 4n- 8 edges.
The technique was invented by Reed, Smith andVetta to show that the problem of odd cycle transversal was solvable in time O(3k kmn), for a graph with n vertices, m edges, and odd cycle traversal number k.
Any graph with n vertices also has at most 3n/3 maximal independent sets.
Moon& Moser(1965) showed that any graph with n vertices has at most 3n/3 maximal cliques.
A graph with n vertices and pathwidth p can be embedded into a three-dimensional grid of size p× p× n in such a way that no two edges(represented as straight line segments between grid points) intersect each other.
It is also true that every graph with n vertices has intersection number at most n2/4.
Alternative algorithms are now known that can determine whether a graph is strongly chordal and, if so, construct a strong perfectelimination ordering more efficiently, in time O(min(n2,(n+ m) log n)) for a graph with n vertices and m edges.
The complete graph with n vertices has connectivity n- 1, as implied by the first definition.
As a consequence,they show that every thrackleable graph with n vertices has at most 2n- 3 edges.
Every maximal outerplanar graph with n vertices has exactly 2n- 3 edges, and every bounded face of a maximal outerplanar graph is a triangle.
The conjecture was recently proved,showing that every cubic bridgeless graph with n vertices has at least 2n/3656 perfect matchings.
In graph theory, a nested triangles graph with n vertices is a planar graph formed from a sequence of n/3 triangles, by connecting pairs of corresponding vertices on consecutive triangles in the sequence.
Holes(and antiholes in graphs without chordless cycles of length 5) in a graph with n vertices and m edges may be detected in time n+m2.
The kth power of a graph with n vertices and m edges may be computed in time O(mn) by performing a breadth first search starting from each vertex to determine the distances to all other vertices. .
The number z(n, 2)asks for the maximum number of edges in a bipartite graph with n vertices on each side that has no 4-cycle its girth is six or more.
In a well-covered graph with n vertices, the size of a maximum independent set is at most n/2, so very well covered graphs are the well covered graphs in which the maximum independent set size is as large as possible.
In more detail, as any n-vertex forest hasat most n-1 edges, the arboricity of a graph with n vertices and m edges is at least⌈ m/( n- 1)⌉{\displaystyle\lceil m/(n-1)\rceil.
For instance the facts that any planar graph with n vertices has at most 3n- 6 edges(except for graphs with fewer than 3 vertices), and that any subgraph of a planar graph is planar, together imply that the planar graphs are(3,6)-sparse.
For, in one direction, a bipartite graph with z(n; t) edges andwith n vertices on each side of its bipartition can be reduced to a graph with n vertices and(in expectation) z(n; t)/4 edges, by choosing n/2 vertices uniformly at random from each side.
They also show that this median of a set S of vertices in a median graph satisfies the Condorcet criterion for the winner of an election: compared to any other vertex, it is closer to a majority of the vertices in S. As with partial cubes more generally,every median graph with n vertices has at most(n/2) log2 n edges.
It is straightforward to verify that a given graph with n vertices and m edges is claw-free in time O(n4), by testing each 4-tuple of vertices to determine whether they induce a claw.

Separators can be used to show that the n-vertex planar graphs have universal graphs with n vertices and O(n3/2) edges.
In the other direction, a bound on the number of edges implies a much weaker bound on the queue number: graphs with n vertices and m edges have queue number at most O√m.
The original algorithm for planar branchwidth,by Paul Seymour and Robin Thomas, took time O(n2) on graphs with n vertices, and their algorithm for constructing a branch decomposition of this width took time On4.
