(66−27, 66, 26523)-Net in Base 8 — Upper bound on s

There is no (39, 66, 26524)-net in base 8, because

1 times m-reduction [i] would yield (39, 65, 26524)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 50231 193661 224910 991389 688941 771411 564156 988862 362166 719460 > 8⁶⁵ [i]
