When is the cayley graph of a semigroup isomorphic to the cayley graph of a group

Mathematica Slovaca, 2017
Abstract It is well known that Cayley graphs of groups are automatically vertex-transitive. A pioneer result of Kelarev and Praeger implies that Cayley graphs of semigroups can be regarded as a source of possibly new vertex-transitive graphs.

Cayley Graph Automatic Groups Are Not Necessarily Cayley Graph Biautomatic

Lecture Notes in Computer Science, 2012
We show that there are Cayley graph automatic groups that are not Cayley graph biautomatic. In addition, we show that there are Cayley graph automatic groups with undecidable Conjugacy Problem and that the Isomorphism Problem is undecidable in the class of Cayley graph automatic groups.

Embedding graphs in Cayley graphs

Graphs and Combinatorics, 1987
Over ten years ago Babai showed that for any graph Y and for any sufficiently large group G, there is a Cayley graph X of G such that Y is an induced subgraph of X. The bounds given by him for \(| G|\) have been recently reduced by Babai and Sós to approximately \(9.5| Y|^ 3\).
