(58−39, 58, 130921)-Net in Base 128 — Upper bound on s

There is no (19, 58, 130922)-net in base 128, because

1 times m-reduction [i] would yield (19, 57, 130922)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 1 291197 599639 131648 369556 433087 086331 560699 671984 822646 910957 172593 845100 854723 038835 996720 945741 359539 055861 510696 957272 > 128⁵⁷ [i]
