(140−106, 140, 821)-Net in Base 9 — Upper bound on s

There is no (34, 140, 822)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 40 485381 362353 627056 631015 194881 781568 081539 493633 868609 071340 092559 584774 622124 668709 634224 439686 030854 172662 354296 060043 708595 154929 > 9¹⁴⁰ [i]
