(116, 147, 141472)-Net in Base 3 — Upper bound on s
There is no (116, 147, 141473)-net in base 3, because
- 1 times m-reduction [i] would yield (116, 146, 141473)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 4567 950500 179650 704642 685366 923861 336868 500129 992734 291648 219032 616171 > 3146 [i]
