(154−17, 154, 2152218)-Net in Base 2 — Upper bound on s
There is no (137, 154, 2152219)-net in base 2, because
- 1 times m-reduction [i] would yield (137, 153, 2152219)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 11417 991875 258361 996829 594181 325247 816134 539555 > 2153 [i]
