(57, 57+83, 3441)-Net in Base 9 — Upper bound on s

There is no (57, 140, 3442)-net in base 9, because

1 times m-reduction [i] would yield (57, 139, 3442)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 4 372565 429564 615868 105034 167914 377230 661140 545828 406876 712528 395762 096257 513450 168655 000066 515623 281211 414173 472293 093419 119763 577105 > 9¹³⁹ [i]
