In this work, given (R, m) a finite commutative local ring with identity and k ∈ N with (k, |R|) = 1, we study the number of cliques of any size in theUsing the known fact that the graph G R (k) can be obtained by blowing-up the vertices of G Fq (k) a number |m| of times, we reduce the study of the number of cliques in G R (k) over the local ring R to the computation of the number of cliques of G R/m (k) over the finite residue field R/m F q . In this way, using known numbers of -cliques of generalized Paley graphs (k = 2, 3, 4 and = 3, 4), we obtain several explicit results for the number of -cliques over finite commutative local rings with identity.
