Best Known (17, s)-Sequences in Base 3
(17, 27)-Sequence over F3 — Constructive and digital
Digital (17, 27)-sequence over F3, using
- t-expansion [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
(17, 42)-Sequence in Base 3 — Upper bound on s
There is no (17, 43)-sequence in base 3, because
- net from sequence [i] would yield (17, m, 44)-net in base 3 for arbitrarily large m, but
- m-reduction [i] would yield (17, 171, 44)-net in base 3, but
- extracting embedded OOA [i] would yield OOA(3171, 44, S3, 4, 154), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 685027 211508 324515 777792 095033 732379 709657 564813 491328 565171 830353 981268 593042 103819 / 155 > 3171 [i]
- extracting embedded OOA [i] would yield OOA(3171, 44, S3, 4, 154), but
- m-reduction [i] would yield (17, 171, 44)-net in base 3, but
