Abstract

A walk of length n in a graph is consistent if there exists an automorphism of the graph that maps the initial n vertices to the final n vertices of the walk, preserving their order. In this paper we find some sufficient conditions for a consistent walk in an arc-transitive graph to have trivial pointwise stabilizer. We show that in that case, the size of the smallest generating set of the automorphism group is bounded by the valence of the graph.

期刊介绍： Discrete Mathematics provides a common forum for significant research in many areas of discrete mathematics and combinatorics. Among the fields covered by Discrete Mathematics are graph and hypergraph theory, enumeration, coding theory, block designs, the combinatorics of partially ordered sets, extremal set theory, matroid theory, algebraic combinatorics, discrete geometry, matrices, and discrete probability theory. Items in the journal include research articles (Contributions or Notes, depending on length) and survey/expository articles (Perspectives). Efforts are made to process the submission of Notes (short articles) quickly. The Perspectives section features expository articles accessible to a broad audience that cast new light or present unifying points of view on well-known or insufficiently-known topics.
