(174, 174+25, 490163)-Net in Base 2 — Upper bound on s
There is no (174, 199, 490164)-net in base 2, because
- 1 times m-reduction [i] would yield (174, 198, 490164)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 401740 883657 100137 741072 919558 496984 750511 819475 048772 674732 > 2198 [i]
