Welcome to the page of the Combinatorics Seminar of the Department of Mathematics of the University Sapienza, Rome.
During the year 20072008 the seminar meets usually on Thursdays in Aula di Consiglio.
Next meetings:
Thursday; 5 June 2008, 3pm, Aula di Consiglio
I will discuss the following unpublished theorem of Conway, and generalizations: If a dvalent graph has an edgetransitive automorphism group G, then G has exactly d1 orbits in its action on those ordered cycles of the graph that also are cycles of permutations in G.
