(221−127, 221, 191)-Net in Base 2 — Upper bound on s
There is no (94, 221, 192)-net in base 2, because
- 1 times m-reduction [i] would yield (94, 220, 192)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 1 701024 054669 856933 221350 456075 388497 105577 160100 086026 813584 054875 > 2220 [i]
