Best Known (18, 122, s)-Nets in Base 3
(18, 122, 28)-Net over F3 — Constructive and digital
Digital (18, 122, 28)-net over F3, using
- t-expansion [i] based on digital (15, 122, 28)-net over F3, using
- net from sequence [i] based on digital (15, 27)-sequence over F3, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F3 with g(F) = 15 and N(F) ≥ 28, using
- net from sequence [i] based on digital (15, 27)-sequence over F3, using
(18, 122, 49)-Net in Base 3 — Upper bound on s
There is no (18, 122, 50)-net in base 3, because
- 26 times m-reduction [i] would yield (18, 96, 50)-net in base 3, but
- extracting embedded OOA [i] would yield OOA(396, 50, S3, 2, 78), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 629905 858672 458293 489008 047491 314888 858131 415779 / 79 > 396 [i]
- extracting embedded OOA [i] would yield OOA(396, 50, S3, 2, 78), but
