(40, 40+49, 3850)-Net in Base 9 — Upper bound on s

There is no (40, 89, 3851)-net in base 9, because

1 times m-reduction [i] would yield (40, 88, 3851)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 942641 503213 965804 956225 834541 767594 070181 023012 242894 366034 474102 154252 998285 922881 > 9⁸⁸ [i]
