(167, 198, 57693)-Net in Base 2 — Upper bound on s
There is no (167, 198, 57694)-net in base 2, because
- 1 times m-reduction [i] would yield (167, 197, 57694)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 200883 067354 215469 833309 742366 864714 743697 326537 964611 539468 > 2197 [i]
