(47, 47+173, 61)-Net in Base 2 — Upper bound on s
There is no (47, 220, 62)-net in base 2, because
- 41 times m-reduction [i] would yield (47, 179, 62)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2179, 62, S2, 3, 132), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 122 599643 269271 108668 667762 172024 734689 499129 774688 174080 / 133 > 2179 [i]
- extracting embedded OOA [i] would yield OOA(2179, 62, S2, 3, 132), but
