(73, 73+71, 585)-Net in Base 3 — Upper bound on s

There is no (73, 144, 586)-net in base 3, because

1 times m-reduction [i] would yield (73, 143, 586)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 177 298970 858720 710402 133385 138468 654523 645861 416821 456424 065393 647473 > 3¹⁴³ [i]
