Best Known (39, s)-Sequences in Base 81
(39, 729)-Sequence over F81 — Constructive and digital
Digital (39, 729)-sequence over F81, using
- t-expansion [i] based on digital (36, 729)-sequence over F81, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F81 with g(F) = 36 and N(F) ≥ 730, using
- the Hermitian function field over F81 [i]
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F81 with g(F) = 36 and N(F) ≥ 730, using
(39, 3279)-Sequence in Base 81 — Upper bound on s
There is no (39, 3280)-sequence in base 81, because
- net from sequence [i] would yield (39, m, 3281)-net in base 81 for arbitrarily large m, but
- m-reduction [i] would yield (39, 3279, 3281)-net in base 81, but
- extracting embedded OOA [i] would yield OA(813279, 3281, S81, 3240), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 2777 446989 284709 510564 961725 522798 165397 527154 745346 781202 697478 500075 605650 241673 446945 350517 449784 143132 584592 515650 191522
