(161, 184, 500086)-Net in Base 2 — Upper bound on s
There is no (161, 184, 500087)-net in base 2, because
- 1 times m-reduction [i] would yield (161, 183, 500087)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 12 260222 091463 089622 562142 315282 771543 354089 870449 568804 > 2183 [i]
