(177, 200, 1370614)-Net in Base 2 — Upper bound on s
There is no (177, 200, 1370615)-net in base 2, because
- 1 times m-reduction [i] would yield (177, 199, 1370615)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 803471 235553 273154 467924 365571 091196 829665 284816 498947 247748 > 2199 [i]
