Abstract :
A graph Γ is said to be vertex-transitive or edge- transitive
if the automorphism group of Gamma
Gamma
acts transitively on V(Γ)
or E(Γ)
, respectively.
Let Γ=Cay(G,S) be a Cayley graph on G relative to S. Then, Γ is said to be normal edge-transitive, if N Aut(Γ)(G) acts transitively on edges. In this paper, the eigenvalues of normal edge-transitive Cayley graphs of the groups D 2n
and T 4n are given.
