## Abstract Let __G__ be an undirected graph without multiple edges and with a loop at every vertexβ€”the set of edges of __G__ corresponds to a reflexive and symmetric binary relation on its set of vertices. Then __every edge‐preserving map of the set of vertices of G to itself fixes an edge__ [{__f
