(164, 164+35, 22992)-Net in Base 2 — Upper bound on s
There is no (164, 199, 22993)-net in base 2, because
- 1 times m-reduction [i] would yield (164, 198, 22993)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 401861 579802 375674 138476 421584 636301 369022 634839 842427 452874 > 2198 [i]
