(200, 233, 157546)-Net in Base 2 — Upper bound on s
There is no (200, 233, 157547)-net in base 2, because
- 1 times m-reduction [i] would yield (200, 232, 157547)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 6902 063425 962877 248153 538452 834826 839410 780477 005124 378721 847229 503398 > 2232 [i]
