(259−178, 259, 117)-Net in Base 2 — Upper bound on s
There is no (81, 259, 118)-net in base 2, because
- 30 times m-reduction [i] would yield (81, 229, 118)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2229, 118, S2, 2, 148), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 165641 912322 973530 898434 140694 648610 858826 615332 089277 323900 581371 183104 / 149 > 2229 [i]
- extracting embedded OOA [i] would yield OOA(2229, 118, S2, 2, 148), but
