(93−47, 93, 786)-Net in Base 4 — Upper bound on s

There is no (46, 93, 787)-net in base 4, because

1 times m-reduction [i] would yield (46, 92, 787)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 25 166540 559817 642274 360051 841200 586497 808197 064743 991808 > 4⁹² [i]
