(3, 29, 28)-Net over F9 — Constructive and digital
Digital (3, 29, 28)-net over F9, using
- net from sequence [i] based on digital (3, 27)-sequence over F9, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F9 with g(F) = 3 and N(F) ≥ 28, using
- the Hermitian function field over F9 [i]
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F9 with g(F) = 3 and N(F) ≥ 28, using
(3, 29, 57)-Net over F9 — Upper bound on s (digital)
There is no digital (3, 29, 58)-net over F9, because
- 1 times m-reduction [i] would yield digital (3, 28, 58)-net over F9, but
- extracting embedded orthogonal array [i] would yield linear OA(928, 58, F9, 25) (dual of [58, 30, 26]-code), but
- construction Y1 [i] would yield
- OA(927, 31, S9, 25), but
- the linear programming bound shows that M ≥ 25644 034018 340666 323462 064529 / 377 > 927 [i]
- linear OA(930, 58, F9, 27) (dual of [58, 28, 28]-code), but
- discarding factors / shortening the dual code would yield linear OA(930, 39, F9, 27) (dual of [39, 9, 28]-code), but
- residual code [i] would yield OA(93, 11, S9, 3), but
- discarding factors / shortening the dual code would yield linear OA(930, 39, F9, 27) (dual of [39, 9, 28]-code), but
- OA(927, 31, S9, 25), but
- construction Y1 [i] would yield
- extracting embedded orthogonal array [i] would yield linear OA(928, 58, F9, 25) (dual of [58, 30, 26]-code), but
(3, 29, 69)-Net in Base 9 — Upper bound on s
There is no (3, 29, 70)-net in base 9, because
- extracting embedded orthogonal array [i] would yield OA(929, 70, S9, 26), but
- the linear programming bound shows that M ≥ 142987 262234 073920 151202 698779 772123 777873 / 27 836552 119093 > 929 [i]
