Best Known (27, 243, s)-Nets in Base 3
(27, 243, 37)-Net over F3 — Constructive and digital
Digital (27, 243, 37)-net over F3, using
- net from sequence [i] based on digital (27, 36)-sequence over F3, using
- Niederreiter–Xing sequence construction III based on the algebraic function field F/F3 with g(F) = 26, N(F) = 36, and 1 place with degree 2 [i] based on function field F/F3 with g(F) = 26 and N(F) ≥ 36, using an explicitly constructive algebraic function field [i]
(27, 243, 39)-Net over F3 — Digital
Digital (27, 243, 39)-net over F3, using
- net from sequence [i] based on digital (27, 38)-sequence over F3, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F3 with g(F) = 27 and N(F) ≥ 39, using
(27, 243, 65)-Net in Base 3 — Upper bound on s
There is no (27, 243, 66)-net in base 3, because
- 50 times m-reduction [i] would yield (27, 193, 66)-net in base 3, but
- extracting embedded OOA [i] would yield OOA(3193, 66, S3, 3, 166), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 22954 295334 952140 560141 595731 487128 244501 656402 145203 355827 465829 304289 337149 571369 885097 448247 / 167 > 3193 [i]
- extracting embedded OOA [i] would yield OOA(3193, 66, S3, 3, 166), but
