(136−68, 136, 147)-Net in Base 2 — Upper bound on s
There is no (68, 136, 148)-net in base 2, because
- extracting embedded orthogonal array [i] would yield OA(2136, 148, S2, 68), but
- the linear programming bound shows that M ≥ 646 721610 757388 071104 535829 906802 483673 432064 / 6027 > 2136 [i]
