(175−25, 175, 122527)-Net in Base 2 — Upper bound on s
There is no (150, 175, 122528)-net in base 2, because
- 1 times m-reduction [i] would yield (150, 174, 122528)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 23945 913292 335616 710658 708146 461831 203135 922849 391997 > 2174 [i]
