Best Known (57, 220, s)-Nets in Base 2
(57, 220, 42)-Net over F2 — Constructive and digital
Digital (57, 220, 42)-net over F2, using
- t-expansion [i] based on digital (54, 220, 42)-net over F2, using
- net from sequence [i] based on digital (54, 41)-sequence over F2, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F2 with g(F) = 54 and N(F) ≥ 42, using
- net from sequence [i] based on digital (54, 41)-sequence over F2, using
(57, 220, 73)-Net in Base 2 — Upper bound on s
There is no (57, 220, 74)-net in base 2, because
- 6 times m-reduction [i] would yield (57, 214, 74)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2214, 74, S2, 3, 157), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 2 527495 000045 372480 750032 664408 090375 653482 289613 178670 103463 460864 / 79 > 2214 [i]
- extracting embedded OOA [i] would yield OOA(2214, 74, S2, 3, 157), but
