Best Known (33, s)-Sequences in Base 81
(33, 369)-Sequence over F81 — Constructive and digital
Digital (33, 369)-sequence over F81, using
- t-expansion [i] based on digital (16, 369)-sequence over F81, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F81 with g(F) = 16 and N(F) ≥ 370, using
(33, 575)-Sequence over F81 — Digital
Digital (33, 575)-sequence over F81, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F81 with g(F) = 33 and N(F) ≥ 576, using
(33, 2787)-Sequence in Base 81 — Upper bound on s
There is no (33, 2788)-sequence in base 81, because
- net from sequence [i] would yield (33, m, 2789)-net in base 81 for arbitrarily large m, but
- m-reduction [i] would yield (33, 2787, 2789)-net in base 81, but
- extracting embedded OOA [i] would yield OA(812787, 2789, S81, 2754), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 502725 220984 619956 895141 550174 387866 425949 044061 222978 608663 750785 975612 382182 946257 191702 759555 282969 471790 788268 463532 079201
