Best Known (4, 4+81, s)-Nets in Base 25
(4, 4+81, 66)-Net over F25 — Constructive and digital
Digital (4, 85, 66)-net over F25, using
- net from sequence [i] based on digital (4, 65)-sequence over F25, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F25 with g(F) = 4 and N(F) ≥ 66, using
(4, 4+81, 263)-Net in Base 25 — Upper bound on s
There is no (4, 85, 264)-net in base 25, because
- extracting embedded orthogonal array [i] would yield OA(2585, 264, S25, 81), but
- the linear programming bound shows that M ≥ 45289 578748 730074 256474 042827 425892 047621 998663 239338 156108 911410 518602 833447 715326 764893 840860 701634 002056 029104 643641 858274 349942 803382 873535 156250 000000 / 672222 567253 257920 282468 896151 858599 > 2585 [i]
