Abstract
Let G be a group, and S a nonempty subset of G. Then S is productfree if ab is not in S for all a, b in S. We say S is locally maximal productfree if S is productfree and not properly contained in any other productfree set. A natural question is to determine the smallest possible size of a locally maximal productfree set in G. Alternatively, given a positive integer k, one can ask: what is the largest integer n_k such that there is a group of order n_k with a locally maximal productfree set of size k? The groups containing locally maximal productfree sets of sizes 1 and 2 are known, and it has been conjectured that n_3 = 24. The purpose of this paper is to prove this conjecture and hence show that the list of known locally maximal productfree sets of size 3 is complete. We also report some experimental observations about the sequence n_k.
