(188−137, 188, 76)-Net in Base 2 — Upper bound on s
There is no (51, 188, 77)-net in base 2, because
- 40 times m-reduction [i] would yield (51, 148, 77)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2148, 77, S2, 2, 97), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 2854 495385 411919 762116 571938 898990 272765 493248 / 7 > 2148 [i]
- extracting embedded OOA [i] would yield OOA(2148, 77, S2, 2, 97), but
