(167−35, 167, 6218)-Net in Base 2 — Upper bound on s
There is no (132, 167, 6219)-net in base 2, because
- 1 times m-reduction [i] would yield (132, 166, 6219)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 93 701605 352335 346890 927368 499648 604074 560980 357552 > 2166 [i]
