(133−102, 133, 72)-Net over F5 — Constructive and digital
Digital (31, 133, 72)-net over F5, using
- net from sequence [i] based on digital (31, 71)-sequence over F5, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F5 with g(F) = 31 and N(F) ≥ 72, using
(133−102, 133, 270)-Net over F5 — Upper bound on s (digital)
There is no digital (31, 133, 271)-net over F5, because
- 2 times m-reduction [i] would yield digital (31, 131, 271)-net over F5, but
- extracting embedded orthogonal array [i] would yield linear OA(5131, 271, F5, 100) (dual of [271, 140, 101]-code), but
- residual code [i] would yield OA(531, 170, S5, 20), but
- the linear programming bound shows that M ≥ 42216 069885 091800 891878 320552 825927 734375 / 8 765861 509813 289221 > 531 [i]
- residual code [i] would yield OA(531, 170, S5, 20), but
- extracting embedded orthogonal array [i] would yield linear OA(5131, 271, F5, 100) (dual of [271, 140, 101]-code), but
(133−102, 133, 291)-Net in Base 5 — Upper bound on s
There is no (31, 133, 292)-net in base 5, because
- 1 times m-reduction [i] would yield (31, 132, 292)-net in base 5, but
- extracting embedded orthogonal array [i] would yield OA(5132, 292, S5, 101), but
- 8 times code embedding in larger space [i] would yield OA(5140, 300, S5, 101), but
