(200, 223, 5839095)-Net in Base 2 — Upper bound on s
There is no (200, 223, 5839096)-net in base 2, because
- 1 times m-reduction [i] would yield (200, 222, 5839096)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 6 739988 302673 007596 196467 126617 071919 297393 276575 236250 545137 829182 > 2222 [i]
