(140, 140+79, 685)-Net in Base 2 — Upper bound on s
There is no (140, 219, 686)-net in base 2, because
- 1 times m-reduction [i] would yield (140, 218, 686)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 432900 567581 338837 815912 060908 460863 051575 791059 260011 905945 203392 > 2218 [i]
