(46−39, 46, 6102)-Net in Base 128 — Upper bound on s

There is no (7, 46, 6103)-net in base 128, because

1 times m-reduction [i] would yield (7, 45, 6103)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 66812 543578 943370 218481 004999 102215 227748 540684 739888 609170 643125 778836 626311 750553 145550 102508 > 128⁴⁵ [i]
