(205, 205+29, 618646)-Net in Base 2 — Upper bound on s
There is no (205, 234, 618647)-net in base 2, because
- 1 times m-reduction [i] would yield (205, 233, 618647)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 13803 647967 572988 299255 190413 448060 425548 587834 376753 290628 808140 947618 > 2233 [i]
