We denote by $ O_k $ the graph with the $ k $ element subsets of $ I = \\{ 1,2,...,n \\} $ as vertices, where two such vertices are adjacent if they are disjoint. we roll call a graph $ \\Gamma $ a $ VTNC$-graph, if it is a vertex transitive non-Cayley graph. In [7 ] it has been proved that $ O_k $ is a $ VTNC$-graph. The methods which used by the author to obtain the result, need some deep results from permutation group theory. In this paper we will show that $ O_k $ is a $ VTNC$-graph, by using rather elementary facts of number theory and group theory.", "revisions": [ { "version": "v1", "updated": "2017-02-07T16:52:10.000Z" } ], "analyses": { "subjects": [ "05C25", "05C69", "94C15" ], "keywords": [ "odd graph theory", "permutation group theory", "vertex transitive non-cayley graph", "element subsets", "deep results" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
