Symmetric graph

Every connected symmetric graph must thus be both vertex-transitive and edge-transitive and the converse is true for graphs of odd degree. In graph theory a branch of mathematics an undirected graph is called an asymmetric graph if it has no nontrivial symmetries.

This graph is symmetric about its axis.

. Many symmetric properties are well-explored in graph theory especially in graph coloring such as symmetric graphs defined by the automorphism groups symmetric drawing of planar graphs. The second property of graph is symmetry. Any pair of adjacent vertices can be mapped to another by an automorphism since any five-vertex ring can be mapped to.

That is it is symmetric. A t-transitive graph is a graph such that the automorphism group acts transitively on t-arcs but not on t1-arcs. For parabolas the axis of symmetry is a vertical line drawn.

Y is on the graph the point x. Since 1-arcs are simply edges every symmetric graph of degree 3 or more. The axis of Cartesian plane divides the graph in perfect halves is what we call as the symmetry of graph.

However for even degree there. In what follows list any symmetries if any for the displayed graph and state whether the graph shows a function. Formally an automorphism of a.

The smallest zero-symmetric graph is a nonplanar graph with 18 vertices. Y is also on the graph. In the mathematical field of graph theory a zero-symmetric graph is a connected graph in which each vertex has exactly three incident edges.

The axis of symmetry also called the line of symmetry is a line that creates two sides. In graph theory a branch of mathematics a skew-symmetric graph is a directed graph that is isomorphic to its own transpose graph the graph formed by reversing all. WikiMatrix By definition ignoring u1 and u2 a symmetric graph without isolated vertices must also be vertex-transitive.

This graph is symmetric with. 3 However for even degree there exist connected. Every connected symmetric graph must thus be both vertex-transitive and edge-transitive and the converse is true for graphs of odd degree.

Each side is a mirror image. In the mathematical field of graph theory a semi-symmetric graph is an undirected graph that is edge-transitive and regular but not vertex-transitive. The Petersen graph is a cubic symmetric graph.

A graph is symmetric with respect to the y-axis if whenever a point x. For example there are just two distinct 3. A vertex-transitive graph is symmetric if and only if each vertex-stabilizer Gv acts transitively on the set of vertices adjacent to v.

There are 3 rules.
