Amply regular graph products

A regular graph is called amply regular if the number of common neighbours of two adjacent vertices is independent of the choice of these two vertices and the number of common neighbours of 
two vertices at a distance 2 is independent of the choice of these two 
vertices. In this talk we present some results about amply regular 
lexicographic, deleted lexicographic and co-normal graph products.
