(155−19, 155, 587083)-Net in Base 2 — Upper bound on s
There is no (136, 155, 587084)-net in base 2, because
- 1 times m-reduction [i] would yield (136, 154, 587084)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 22836 298804 441593 859873 380324 500321 706566 428201 > 2154 [i]
