(196, 196+33, 132476)-Net in Base 2 — Upper bound on s
There is no (196, 229, 132477)-net in base 2, because
- 1 times m-reduction [i] would yield (196, 228, 132477)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 431 380570 937595 915927 550644 300484 554948 921278 425648 227004 643451 766209 > 2228 [i]
