open-in-new
<p>In <a href="/facts/Graph_theory/VVPCd4TX">graph theory</a>, a circulant graph is an <a href="/facts/Undirected_graph/kw3eIBUe">undirected graph</a> acted on by a <a href="/facts/Cyclic_group/JL5zfFuL">cyclic group</a> of <a href="/facts/Graph_automorphism/If8FTdFE">symmetries</a> which <a href="/facts/Vertex-transitive_graph/042b7rD7">takes any vertex to any other vertex</a>. It is sometimes called a <a href="/facts/Cyclic_graph/IumUWuop">cyclic graph</a>, but this term has other meanings. </p>
