(192, 223, 183213)-Net in Base 2 — Upper bound on s
There is no (192, 223, 183214)-net in base 2, because
- 1 times m-reduction [i] would yield (192, 222, 183214)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 6 740038 638230 713291 901976 926758 404878 514915 901025 885945 285988 394588 > 2222 [i]
