Best Known (20, 20+59, s)-Nets in Base 25

(20, 20+59, 148)-Net over F₂₅ — Constructive and digital

Digital (20, 79, 148)-net over F₂₅, using

t-expansion [i] based on digital (19, 79, 148)-net over F₂₅, using
- net from sequence [i] based on digital (19, 147)-sequence over F₂₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅ with g(F) = 19 and N(F) ≥ 148, using
    - a function field by GarcÃa and Quoos [i]

(20, 20+59, 171)-Net over F₂₅ — Digital

Digital (20, 79, 171)-net over F₂₅, using

net from sequence [i] based on digital (20, 170)-sequence over F₂₅, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅ with g(F) = 20 and N(F) ≥ 171, using
  - an algebraic function field by Teo [i]

(20, 20+59, 2783)-Net in Base 25 — Upper bound on s

There is no (20, 79, 2784)-net in base 25, because

1 times m-reduction [i] would yield (20, 78, 2784)-net in base 25, but
- the generalized Rao bound for nets shows that 25^mÂ â‰¥ 11 054119 480947 723220 846905 156373 357180 049306 360676 075905 928963 716808 817891 104209 507271 342964 330707 986340 559105 > 25⁷⁸ [i]
