(198, 231, 144468)-Net in Base 2 — Upper bound on s
There is no (198, 231, 144469)-net in base 2, because
- 1 times m-reduction [i] would yield (198, 230, 144469)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 1725 461236 904330 076677 202527 219760 601381 961826 717714 045489 872143 462505 > 2230 [i]
