(242−189, 242, 68)-Net in Base 2 — Upper bound on s
There is no (53, 242, 69)-net in base 2, because
- 42 times m-reduction [i] would yield (53, 200, 69)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2200, 69, S2, 3, 147), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 70 705273 947395 572123 846332 063011 154510 976931 726442 884753 260544 / 37 > 2200 [i]
- extracting embedded OOA [i] would yield OOA(2200, 69, S2, 3, 147), but
