(181−133, 181, 72)-Net in Base 2 — Upper bound on s
There is no (48, 181, 73)-net in base 2, because
- 42 times m-reduction [i] would yield (48, 139, 73)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2139, 73, S2, 2, 91), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 16 725558 898897 967356 151788 704486 271129 485312 / 23 > 2139 [i]
- extracting embedded OOA [i] would yield OOA(2139, 73, S2, 2, 91), but
