(257−175, 257, 118)-Net in Base 2 — Upper bound on s
There is no (82, 257, 119)-net in base 2, because
- 26 times m-reduction [i] would yield (82, 231, 119)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2231, 119, S2, 2, 149), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 55213 970774 324510 299478 046898 216203 619608 871777 363092 441300 193790 394368 / 15 > 2231 [i]
- extracting embedded OOA [i] would yield OOA(2231, 119, S2, 2, 149), but
