(247−147, 247, 196)-Net in Base 2 — Upper bound on s
There is no (100, 247, 197)-net in base 2, because
- 1 times m-reduction [i] would yield (100, 246, 197)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 139 706914 193989 061032 049441 677824 502379 537241 610486 989312 433127 370553 486560 > 2246 [i]
