Best Known (20, 20+45, s)-Nets in Base 2
(20, 20+45, 20)-Net over F2 — Constructive and digital
Digital (20, 65, 20)-net over F2, using
- t-expansion [i] based on digital (19, 65, 20)-net over F2, using
- net from sequence [i] based on digital (19, 19)-sequence over F2, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F2 with g(F) = 19 and N(F) ≥ 20, using
- net from sequence [i] based on digital (19, 19)-sequence over F2, using
(20, 20+45, 33)-Net in Base 2 — Upper bound on s
There is no (20, 65, 34)-net in base 2, because
- 2 times m-reduction [i] would yield (20, 63, 34)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(263, 34, S2, 2, 43), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 110 680464 442257 309696 / 11 > 263 [i]
- extracting embedded OOA [i] would yield OOA(263, 34, S2, 2, 43), but
