On Isomorphisms of Connected Cayley Graphs, II
TL;DR: For every primep, the problem of determining which Cayley graphs and digraphs for a given group are CI-graphs is studied, and infinitely many finite groups such that p(G)=pand is neither a connectedp-DCI-group nor a connected 2p-CI-group, which provides solutions for several open problems in this area.

Classifying a family of edge-transitive metacirculant graphs
TL;DR: In this article, a characterization of edge-transitive Cayley graphs of Frobenius groups is given, with p,q odd prime, of valency coprime to p.
Semiregular automorphisms of cubic vertex transitive graphs
Cai Heng Li
- 14 Feb 2008
TL;DR: In this paper, it was shown that for a connected cubic graph F, a vertex transitive group G < Aut Γ contains a large semiregular subgroup, confirming a conjecture of Cameron and Sheehan (2001).
The finite groups with the 2-dci property
TL;DR: In this paper, all finite groups which have the 2-DCI property but do not have the 1-; DCI property are completely classified and all groups with the 2DCI and 1DCI properties are considered.

Relative difference sets fixed by inversion and Cayley graphs
Yu Qing Chen,Cai Heng Li +1 more
TL;DR: This work presents a construction of a (30, 2, 29, 14)-relative difference set fixed by inversion in the smallest finite simple group--the alternating group A5, which is the first example known of relative difference sets in the finite simple groups with a non-trivial forbidden subgroup.
