Best Known (4, 4+47, s)-Nets in Base 16
(4, 4+47, 45)-Net over F16 — Constructive and digital
Digital (4, 51, 45)-net over F16, using
- net from sequence [i] based on digital (4, 44)-sequence over F16, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F16 with g(F) = 4 and N(F) ≥ 45, using
(4, 4+47, 187)-Net in Base 16 — Upper bound on s
There is no (4, 51, 188)-net in base 16, because
- 1 times m-reduction [i] would yield (4, 50, 188)-net in base 16, but
- extracting embedded orthogonal array [i] would yield OA(1650, 188, S16, 46), but
- the linear programming bound shows that M ≥ 1091 765195 970395 890315 693716 185672 889915 998980 326190 139213 332068 390649 880226 998373 056512 / 657 761924 179275 666558 951967 > 1650 [i]
- extracting embedded orthogonal array [i] would yield OA(1650, 188, S16, 46), but
