(221−79, 221, 712)-Net in Base 2 — Upper bound on s
There is no (142, 221, 713)-net in base 2, because
- 1 times m-reduction [i] would yield (142, 220, 713)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 1 750789 194984 797099 892653 736388 634888 673200 803737 418544 680382 338560 > 2220 [i]
