(196, 223, 783541)-Net in Base 2 — Upper bound on s
There is no (196, 223, 783542)-net in base 2, because
- 1 times m-reduction [i] would yield (196, 222, 783542)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 6 740098 382427 222790 784526 732227 984264 814557 442821 472060 534569 630850 > 2222 [i]
