Actually, this is what is proved in the paper. Indeed, it is possible to find examples of sets Q for which 5040 does not divide r(Q). J. Leech has proposed r({210« + 199,« = 1(1)8}) = 23325272 and R. A. Morris r({ll, 17, 19, 23, 29, 41, 47, 53}) = 2332 • 5 • 711 • 17. As a matter of fact, the smallest p for which there exists a set Q such that r(Q) = p and 2 || P is p for instance. 3||/> = 2332 • 5 • 7 • 11 with Q = ({17, 19, 23, 29, 37, 41, 47, 59})
