(177−130, 177, 36)-Net over F2 — Digital
Digital (47, 177, 36)-net over F2, using
- net from sequence [i] based on digital (47, 35)-sequence over F2, using

(177−130, 177, 71)-Net in Base 2 — Upper bound on s
There is no (47, 177, 72)-net in base 2, because
- 40 times m-reduction [i] would yield (47, 137, 72)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2137, 72, S2, 2, 90), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 22 300745 198530 623141 535718 272648 361505 980416 / 91 > 2137 [i]
- extracting embedded OOA [i] would yield OOA(2137, 72, S2, 2, 90), but
