(95, 118, 4145920)-Net in Base 4 — Upper bound on s

There is no (95, 118, 4145921)-net in base 4, because

1 times m-reduction [i] would yield (95, 117, 4145921)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 27607 006452 386249 344344 240402 561359 723336 155705 541993 378544 502443 122944 > 4¹¹⁷ [i]
