(134, 149, 7826224)-Net in Base 2 — Upper bound on s
There is no (134, 149, 7826225)-net in base 2, because
- 1 times m-reduction [i] would yield (134, 148, 7826225)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 356 812166 504191 469446 591687 418554 780827 856896 > 2148 [i]
