摘 要：
The question of whether a group can be represented as the automorphism group of a graph was addressed in the early stages of graph theory. If a group G is isomorphic to the automorphism group of a Cayley graph Γ of G, then Γ is said to be a Graphical Regular Representation (GRR) of G. A classic result, established in the 1970s through a series of papers by various authors, determines which groups possess GRRs. In this talk, I will delve into the more recent developments in GRRs, encompassing asymptotic enumeration, GRRs with prescribed valency, and some variations of GRRs.
