Vertex-transitive graph — In mathematics, a vertex transitive graph is a graph G such that, given any two vertices v1 and v2 of G , there is some automorphism : f : V(G) → V(G) such that : f (v1) = v2. In other words, a graph is vertex transitive if its automorphism group … Wikipedia

Graph automorphism — In graph theoretical mathematics, an automorphism of a graph is a form of symmetry in which the graph is mapped onto itself while preserving the edge vertex connectivity.Formally, an automorphism of a graph G = ( V , E ) is a permutation sigma;… … Wikipedia
Holt graph — In the Holt graph, all vertices are equivalent, and all edges are equivalent, but edges are not necessarily equivalent to their inverses. Named after Derek F. Holt Vertices 27 … Wikipedia
Line graph — This article is about the mathematical concept. For statistical presentation method, see line chart. In graph theory, the line graph L(G) of undirected graph G is another graph L(G) that represents the adjacencies between edges of G. The name… … Wikipedia

Edge contraction — In graph theory, an edge contraction is an operation which removes an edge from a graph while simultaneously merging together the two vertices it previously connected. Edge contraction is a fundamental operation in the theory of graph minors.… … Wikipedia
Algebraic graph theory — is a branch of mathematics in which algebraic methods are applied to problems about graphs. In one sense, algebraic graph theory studies graphs in connection with linear algebra. Especially, it studies the spectrum of the adjacency matrix, the… … Wikipedia
