Enumeration of Cayley graphs over a nonabelian group of order $8 p$

Bei Ye, Xiaogang Liu, Jing Wang

Let $T_{8 p} = ⟨ a, b ∣ a^{2 p} = b^{8} = e, a^{p} = b^{4}, b^{- 1} ab = a^{- 1} ⟩$ be a nonabelian group of order $8 p$ , where $p$ is an odd prime number. In this paper, we give…

Integral Cayley graphs over a nonabelian group of order $8 n$

Bei Ye, Xiaogang Liu

A graph is called an integral graph when all eigenvalues of its adjacency matrix are integers. We study which Cayley graphs over a nonabelian group $$ T_{8n}=\left\langle a,b\mid a…
