(231−85, 231, 674)-Net in Base 2 — Upper bound on s
There is no (146, 231, 675)-net in base 2, because
- 1 times m-reduction [i] would yield (146, 230, 675)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 1740 747194 546656 479578 469205 509081 403938 950184 604495 820888 832387 689648 > 2230 [i]
