(139, 166, 37493)-Net in Base 2 — Upper bound on s
There is no (139, 166, 37494)-net in base 2, because
- 1 times m-reduction [i] would yield (139, 165, 37494)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 46 782388 543941 867913 639213 977876 323560 799030 308842 > 2165 [i]
