摘要:
A hypergraph is s-arc transitive if its automorphism group acts transitively on the set of its s-arcs. In this paper, We Study s-arc transitive hypergraphs. We show that if a hypergraph has degree at least three and all edges of sizes at least three, then s <= 5. Besides, given an s-arc transitive hypergraph, we prove that there are infinitely many s-arc transitive hypergraphs that cover the given one. These results extend to hypergraph classical results by Tutte, Weiss and Biggs for graphs. (c) 2007 Elsevier Ltd. All rights reserved.
