Circuits in cayley digraphs of finite abelian groups

Journal of Graph Theory, 1990
AbstractWe find all possible lengths of circuits in Cayley digraphs of two‐generated abelian groups over the two‐element generating sets and over certain three‐element generating sets.

On isomorphisms of Cayley digraphs on dicyclic groups

Australas. J Comb., 1997
Summary: We prove that for any \(m\in\{1,2,3\}\), the dicyclic group \(B_{4n}\) \((n\neq 2)\) is an \(m\)-DCI group if and only if \(n\) is odd.

The automorphism groups of circulant digraphs of degree 3

Ars Comb., 1996
Assume \(S \subseteq Z_n\) and denote by \(C_n(S)\) the digraph with vertices \(Z_n\) and arcs \((i,i+s)\), \(i \in Z_n\), \(s \in S\). Denote by \(L(Z_n)\) the group of translations \(i\to a+i\) and by \(\Omega (S)\) the stabilizer of \(\Aut C_n(S)\) at zero, i.e. \(\Omega (S) = \{\tau \in \Aut C_n(S)\mid \tau (0) = 0\}\).

Isomorphisms and automorphism groups of a class of Cayley digraphs on abelian groups

Australas. J Comb., 1997
Finite abelian groups are considered. The elements of the cyclic group \(Z_n\) are represented by the integers \(0,1,2,\dots,n- 1\) in appropriate manner. Let \(S\) be a subset of \(Z_n\). Let \(D(S)\) be the difference of the maximal and minimal element of \(S\).
