Abstract

Consider the Cayley graph of the cyclic group of prime order q with k uniformly chosen generators. For fixed k, we prove that the diameter of said graph is asymptotically (in q) of order k√q. This answers a question of Benjamini. The same also holds when the generating set is taken to be a symmetric set of size 2k.
