(6, 6+21, 10733)-Net in Base 128 — Upper bound on s

There is no (6, 27, 10734)-net in base 128, because

1 times m-reduction [i] would yield (6, 26, 10734)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 6 133975 926202 828974 782205 210183 846202 395260 690937 612966 > 128²⁶ [i]
