(12, 12+23, 29808)-Net in Base 64 — Upper bound on s

There is no (12, 35, 29809)-net in base 64, because

1 times m-reduction [i] would yield (12, 34, 29809)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 25 718224 920576 606691 337511 296323 705832 738210 020140 302908 841680 > 64³⁴ [i]
