Abstract: It is shown that for each integer , there exists a set of positive integers containing no arithmetic progression of k terms, such that , with a finite number of exceptional k for each real . This result is shown to be superior to that attainable with other sets in the literature, in particular Rankin's sets , which have the highest known asymptotic density for sets of positive integers containing no arithmetic progression of k terms.
