(210, 210+33, 242982)-Net in Base 2 — Upper bound on s
There is no (210, 243, 242983)-net in base 2, because
- 1 times m-reduction [i] would yield (210, 242, 242983)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 7 067513 109081 214584 415689 885145 265476 052041 407980 668174 471418 651776 099470 > 2242 [i]
