(52, 52+163, 67)-Net in Base 2 — Upper bound on s
There is no (52, 215, 68)-net in base 2, because
- 18 times m-reduction [i] would yield (52, 197, 68)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2197, 68, S2, 3, 145), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 19 283256 531107 883306 503545 108093 951230 266435 925393 514023 616512 / 73 > 2197 [i]
- extracting embedded OOA [i] would yield OOA(2197, 68, S2, 3, 145), but
