(184, 184+33, 78761)-Net in Base 2 — Upper bound on s
There is no (184, 217, 78762)-net in base 2, because
- 1 times m-reduction [i] would yield (184, 216, 78762)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 105322 426067 338720 294920 812255 886090 024914 614069 320523 808977 431434 > 2216 [i]
