(1, 52, 38)-Net over F27 — Constructive and digital
Digital (1, 52, 38)-net over F27, using
- net from sequence [i] based on digital (1, 37)-sequence over F27, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F27 with g(F) = 1 and N(F) ≥ 38, using
(1, 52, 80)-Net over F27 — Upper bound on s (digital)
There is no digital (1, 52, 81)-net over F27, because
- 24 times m-reduction [i] would yield digital (1, 28, 81)-net over F27, but
- extracting embedded orthogonal array [i] would yield linear OA(2728, 81, F27, 27) (dual of [81, 53, 28]-code), but
- dual of a near-MDS code is again a near-MDS code [i] would yield linear OA(2753, 81, F27, 52) (dual of [81, 28, 53]-code), but
- discarding factors / shortening the dual code would yield linear OA(2753, 56, F27, 52) (dual of [56, 3, 53]-code), but
- dual of a near-MDS code is again a near-MDS code [i] would yield linear OA(2753, 81, F27, 52) (dual of [81, 28, 53]-code), but
- extracting embedded orthogonal array [i] would yield linear OA(2728, 81, F27, 27) (dual of [81, 53, 28]-code), but
(1, 52, 101)-Net in Base 27 — Upper bound on s
There is no (1, 52, 102)-net in base 27, because
- 12 times m-reduction [i] would yield (1, 40, 102)-net in base 27, but
- extracting embedded orthogonal array [i] would yield OA(2740, 102, S27, 39), but
- the linear programming bound shows that M ≥ 1 433148 992150 275824 215814 861808 530567 427328 321769 353624 967879 / 794 > 2740 [i]
- extracting embedded orthogonal array [i] would yield OA(2740, 102, S27, 39), but
