چکیده
|
A simple undirected graph is said to be semisymmetric if it is regular and edge-transitive but notvertex-transitive. let p be a prime. then, by malnic et al. [18, 21 and 22], there exists a unique cubicsemisymmetric cubic graph of order 2p3 and by feng et al. [3] a cubic semisymmetric graph of order 6p3exists if and only if p − 1 is divisible by 3. in this paper, we prove that every cubic edge-transitive graphof order 12p3 is vertex-transitive and so there is no cubic semisymmetric graph of order 12p3
