(184, 184+27, 413217)-Net in Base 2 — Upper bound on s
There is no (184, 211, 413218)-net in base 2, because
- 1 times m-reduction [i] would yield (184, 210, 413218)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 1645 543162 810749 621115 576275 839513 691590 664638 006263 751310 102072 > 2210 [i]
