- Niederreiter–Xing sequence construction III based on function field F4/F3 with g(F4) = 79, N(F4) ≥ 2, and N(F4) + N2(F4) ≥ 112 from GarcÃa–Stichtenoth tower as constant field extension [i]
(228, 162)-Sequence over F3 — Digital
Digital (228, 162)-sequence over F3, using
- t-expansion [i] based on digital (151, 162)-sequence over F3, using

(228, 470)-Sequence in Base 3 — Upper bound on s
There is no (228, 471)-sequence in base 3, because
- net from sequence [i] would yield (228, m, 472)-net in base 3 for arbitrarily large m, but
- m-reduction [i] would yield (228, 2353, 472)-net in base 3, but
- extracting embedded OOA [i] would yield OOA(32353, 472, S3, 5, 2125), but

- extracting embedded OOA [i] would yield OOA(32353, 472, S3, 5, 2125), but
- m-reduction [i] would yield (228, 2353, 472)-net in base 3, but
