(70, 137, 577)-Net in Base 3 — Upper bound on s

There is no (70, 137, 578)-net in base 3, because

1 times m-reduction [i] would yield (70, 136, 578)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 80616 339038 374256 335133 591464 274695 625277 335258 453320 143182 339397 > 3¹³⁶ [i]
