Best Known (37, s)-Sequences in Base 64
(37, 512)-Sequence over F64 — Constructive and digital
Digital (37, 512)-sequence over F64, using
- t-expansion [i] based on digital (28, 512)-sequence over F64, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F64 with g(F) = 28 and N(F) ≥ 513, using
- the Hermitian function field over F64 [i]
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F64 with g(F) = 28 and N(F) ≥ 513, using
(37, 539)-Sequence over F64 — Digital
Digital (37, 539)-sequence over F64, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F64 with g(F) = 37 and N(F) ≥ 540, using
(37, 2457)-Sequence in Base 64 — Upper bound on s
There is no (37, 2458)-sequence in base 64, because
- net from sequence [i] would yield (37, m, 2459)-net in base 64 for arbitrarily large m, but
- m-reduction [i] would yield (37, 4915, 2459)-net in base 64, but
- extracting embedded OOA [i] would yield OOA(644915, 2459, S64, 2, 4878), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 1 971040 087220 852318 442733 170282 243303 749419 521384 077473 666810 901713 411250 588778 440847 630249 168498 381499 086042 438079 245648 921234
