(165, 165+29, 85362)-Net in Base 2 — Upper bound on s
There is no (165, 194, 85363)-net in base 2, because
- 1 times m-reduction [i] would yield (165, 193, 85363)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 12555 292490 139105 256662 821444 092031 615026 096243 210853 207532 > 2193 [i]
