(26−19, 26, 23293)-Net in Base 128 — Upper bound on s

There is no (7, 26, 23294)-net in base 128, because

1 times m-reduction [i] would yield (7, 25, 23294)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 47901 607410 173246 490554 588059 884102 111262 101666 569047 > 128²⁵ [i]
