Best Known (1, 1+33, s)-Nets in Base 27
(1, 1+33, 38)-Net over F27 — Constructive and digital
Digital (1, 34, 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, 1+33, 80)-Net over F27 — Upper bound on s (digital)
There is no digital (1, 34, 81)-net over F27, because
- 6 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, 1+33, 120)-Net in Base 27 — Upper bound on s
There is no (1, 34, 121)-net in base 27, because
- extracting embedded orthogonal array [i] would yield OA(2734, 121, S27, 33), but
- the linear programming bound shows that M ≥ 46 141350 013558 407158 912811 690540 504188 533342 311419 979225 / 9 825743 > 2734 [i]
