Best Known (2, s)-Sequences in Base 5
(2, 11)-Sequence over F5 — Constructive and digital
Digital (2, 11)-sequence over F5, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F5 with g(F) = 2 and N(F) ≥ 12, using
(2, 14)-Sequence in Base 5 — Upper bound on s
There is no (2, 15)-sequence in base 5, because
- net from sequence [i] would yield (2, m, 16)-net in base 5 for arbitrarily large m, but
- m-reduction [i] would yield (2, 19, 16)-net in base 5, but
- extracting embedded OOA [i] would yield OOA(519, 16, S5, 2, 17), but
- the linear programming bound for OOAs shows that M ≥ 3124 237060 546875 / 149 > 519 [i]
- extracting embedded OOA [i] would yield OOA(519, 16, S5, 2, 17), but
- m-reduction [i] would yield (2, 19, 16)-net in base 5, but
