(80, 163, 580)-Net in Base 3 — Upper bound on s

There is no (80, 163, 581)-net in base 3, because

1 times m-reduction [i] would yield (80, 162, 581)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 208136 624481 733552 591021 259481 907531 867278 663794 657675 091670 474367 459096 262507 > 3¹⁶² [i]
