(177−27, 177, 67416)-Net in Base 2 — Upper bound on s
There is no (150, 177, 67417)-net in base 2, because
- 1 times m-reduction [i] would yield (150, 176, 67417)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 95788 397357 001103 712301 667178 223787 838873 503790 522600 > 2176 [i]
