(33, 33+39, 2672)-Net in Base 8 — Upper bound on s

There is no (33, 72, 2673)-net in base 8, because

1 times m-reduction [i] would yield (33, 71, 2673)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 13206 340540 856231 790445 337708 425431 475347 714090 362673 836925 009184 > 8⁷¹ [i]
