Best Known (4, 4+77, s)-Nets in Base 25
(4, 4+77, 66)-Net over F25 — Constructive and digital
Digital (4, 81, 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+77, 271)-Net in Base 25 — Upper bound on s
There is no (4, 81, 272)-net in base 25, because
- extracting embedded orthogonal array [i] would yield OA(2581, 272, S25, 77), but
- the linear programming bound shows that M ≥ 296 675605 806859 748505 162673 034435 115258 648581 017538 394634 857614 710688 110419 391467 911583 863220 751939 183267 298361 101893 533486 872911 453247 070312 500000 / 1705 317125 850348 439457 882817 604799 > 2581 [i]
