(184−27, 184, 97926)-Net in Base 2 — Upper bound on s
There is no (157, 184, 97927)-net in base 2, because
- 1 times m-reduction [i] would yield (157, 183, 97927)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 12 261588 799521 812601 634705 529933 065137 530560 641551 071040 > 2183 [i]
