Let G be a permutation group on a set X. A subset B of X is a base for G if the pointwise stabilizer of B in G is trivial. The base size of G, denoted b(G), is the smallest size of a base for G. A well known conjecture of Pyber from the early 1990s asserts that there is an absolute constant c such that b(G) is at most c.log G/log n for any primitive group G of degree n. Several special cases have been verified in recent years, and I will report on recent joint work with Akos Seress that establishes the conjecture for all nonaffine groups.
