(144−111, 144, 72)-Net over F5 — Constructive and digital
Digital (33, 144, 72)-net over F5, using
- t-expansion [i] based on digital (31, 144, 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

(144−111, 144, 268)-Net over F5 — Upper bound on s (digital)
There is no digital (33, 144, 269)-net over F5, because
- 1 times m-reduction [i] would yield digital (33, 143, 269)-net over F5, but
- extracting embedded orthogonal array [i] would yield linear OA(5143, 269, F5, 110) (dual of [269, 126, 111]-code), but
- residual code [i] would yield OA(533, 158, S5, 22), but
- the linear programming bound shows that M ≥ 8138 155868 573527 404198 089602 172374 725341 796875 / 64473 857393 675955 668371 > 533 [i]
- residual code [i] would yield OA(533, 158, S5, 22), but
- extracting embedded orthogonal array [i] would yield linear OA(5143, 269, F5, 110) (dual of [269, 126, 111]-code), but
(144−111, 144, 291)-Net in Base 5 — Upper bound on s
There is no (33, 144, 292)-net in base 5, because
- 3 times m-reduction [i] would yield (33, 141, 292)-net in base 5, but
- extracting embedded orthogonal array [i] would yield OA(5141, 292, S5, 108), but
- 8 times code embedding in larger space [i] would yield OA(5149, 300, S5, 108), but
