Given a graph G-(V,E), a vertex subset U C V is called irredundant if every vertex v E U either has no neighbours in U or there exists a vertex w E V\U such that v is the only neighbour of w in U. The irredundant Ramsey number s(m,n) is the smallest N such that any redblue edge colouring of K N yiel
