Best Known (206−185, 206, s)-Nets in Base 2
(206−185, 206, 21)-Net over F2 — Constructive and digital
Digital (21, 206, 21)-net over F2, using
- net from sequence [i] based on digital (21, 20)-sequence over F2, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F2 with g(F) = 21 and N(F) ≥ 21, using
(206−185, 206, 28)-Net in Base 2 — Upper bound on s
There is no (21, 206, 29)-net in base 2, because
- 68 times m-reduction [i] would yield (21, 138, 29)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2138, 29, S2, 5, 117), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 24 391440 060892 869061 054691 860709 145397 166080 / 59 > 2138 [i]
- extracting embedded OOA [i] would yield OOA(2138, 29, S2, 5, 117), but
