Best Known (4, 4+13, s)-Nets in Base 7
(4, 4+13, 13)-Net over F7 — Constructive and digital
Digital (4, 17, 13)-net over F7, using
(4, 4+13, 24)-Net over F7 — Digital
Digital (4, 17, 24)-net over F7, using
- net from sequence [i] based on digital (4, 23)-sequence over F7, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F7 with g(F) = 4 and N(F) ≥ 24, using
(4, 4+13, 86)-Net in Base 7 — Upper bound on s
There is no (4, 17, 87)-net in base 7, because
- 1 times m-reduction [i] would yield (4, 16, 87)-net in base 7, but
- the generalized Rao bound for nets shows that 7m ≥ 35 488794 770317 > 716 [i]
