(67, 134, 147)-Net in Base 2 — Upper bound on s
There is no (67, 134, 148)-net in base 2, because
- 3 times m-reduction [i] would yield (67, 131, 148)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2131, 148, S2, 64), but
- the linear programming bound shows that M ≥ 37846 106847 625102 676119 046386 674320 128891 420672 / 12 104235 > 2131 [i]
- extracting embedded orthogonal array [i] would yield OA(2131, 148, S2, 64), but
