(247−162, 247, 122)-Net in Base 2 — Upper bound on s
There is no (85, 247, 123)-net in base 2, because
- 8 times m-reduction [i] would yield (85, 239, 123)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2239, 123, S2, 2, 154), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 28 269553 036454 149273 332760 011886 696253 239742 350009 903329 945699 220681 916416 / 31 > 2239 [i]
- extracting embedded OOA [i] would yield OOA(2239, 123, S2, 2, 154), but
