will speak on
Finite 2sethomogeneous graphs
at 3pm Friday 19 September in Weatherburn Lecture Theatre.
Abstract:
Let k be a positive integer. A finite graph G is said to be ksethomogeneous if for any two isomorphic subgraphs, A and B, of G, each of order at most k, there is an automorphism of G taking A to B. Clearly, every ksethomogeneous graph is also 2sethomogeneous for k >= 2. We study the 2sethomogeneous graphs. It is shown that a 2sethomogeneous graph G either belongs to some known families of graphs or Aut(G) is an almost simple primitive rank 4 permutation group with exactly one orbital selfpaired.
