(6, 6+17, 18476)-Net in Base 128 — Upper bound on s

There is no (6, 23, 18477)-net in base 128, because

1 times m-reduction [i] would yield (6, 22, 18477)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 22836 565809 678126 950638 259591 145581 384109 203443 > 128²² [i]
