(187−35, 187, 595896)-Net in Base 3 — Upper bound on s
There is no (152, 187, 595897)-net in base 3, because
- 1 times m-reduction [i] would yield (152, 186, 595897)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 55533 650110 001749 516045 457151 470503 394255 871196 732341 129200 054068 506457 614515 552437 140531 > 3186 [i]
