 OFFSET 1,2 COMMENTS 2520 is the largest and last of most highly composite numbers = A072938(7) = A002182(18) = 2520; a(A000005(2520)) = a(48) = 2520 is the last term. A242627(2520*n) = 9. - Reinhard Zumkeller, Jul 16 2014 LINKS Eric Weisstein's World of Mathematics, Highly Composite Number PROG (PARI) divisors(2520) \\ Charles R Greathouse IV, Jun 21 2017 CROSSREFS Cf.
