(8, 8+17, 62157)-Net in Base 128 — Upper bound on s

There is no (8, 25, 62158)-net in base 128, because

1 times m-reduction [i] would yield (8, 24, 62158)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 374 183513 322844 473604 174551 029560 717892 968404 912095 > 128²⁴ [i]
