Best Known (20, 20+23, s)-Nets in Base 25
(20, 20+23, 148)-Net over F25 — Constructive and digital
Digital (20, 43, 148)-net over F25, using
- t-expansion [i] based on digital (19, 43, 148)-net over F25, using
- net from sequence [i] based on digital (19, 147)-sequence over F25, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F25 with g(F) = 19 and N(F) ≥ 148, using
- net from sequence [i] based on digital (19, 147)-sequence over F25, using
(20, 20+23, 215)-Net over F25 — Digital
Digital (20, 43, 215)-net over F25, using
(20, 20+23, 44497)-Net in Base 25 — Upper bound on s
There is no (20, 43, 44498)-net in base 25, because
- 1 times m-reduction [i] would yield (20, 42, 44498)-net in base 25, but
- the generalized Rao bound for nets shows that 25m ≥ 51701 041773 060767 561743 569102 801401 700581 662893 004478 630353 > 2542 [i]
