Best Known (14, s)-Sequences in Base 256
(14, 270)-Sequence over F256 — Constructive and digital
Digital (14, 270)-sequence over F256, using
(14, 512)-Sequence over F256 — Digital
Digital (14, 512)-sequence over F256, using
- t-expansion [i] based on digital (8, 512)-sequence over F256, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F256 with g(F) = 8 and N(F) ≥ 513, using
- K1,1 from the tower of function fields by Niederreiter and Xing based on the tower by GarcÃa and Stichtenoth over F256 [i]
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F256 with g(F) = 8 and N(F) ≥ 513, using
(14, 3854)-Sequence in Base 256 — Upper bound on s
There is no (14, 3855)-sequence in base 256, because
- net from sequence [i] would yield (14, m, 3856)-net in base 256 for arbitrarily large m, but
- m-reduction [i] would yield (14, 3854, 3856)-net in base 256, but
- extracting embedded OOA [i] would yield OA(2563854, 3856, S256, 3840), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 931 507293 840705 726420 410637 940806 242235 236403 634054 807059 607281 560748 149913 736700 329909 748488 371096 435053 183813 702193 872309
