The VC-dimension of random subsets of finite groups

Abstract

For a random subset of a finite group GG of cardinality NN, we consider the VC-dimension of the family of its translates (equivalently the VC-dimension of a random Cayley graph) and prove a law of large numbers as NN\rightarrow\infty. This answers a question of McDonald--Sahay--Wyman.
