Best Known (81−57, 81, s)-Nets in Base 5

(81−57, 81, 51)-Net over F₅ — Constructive and digital

Digital (24, 81, 51)-net over F₅, using

t-expansion [i] based on digital (22, 81, 51)-net over F₅, using
- net from sequence [i] based on digital (22, 50)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₅ with g(F) = 22 and N(F) ≥ 51, using
    - an explicitly constructive algebraic function field [i]

(81−57, 81, 55)-Net over F₅ — Digital

Digital (24, 81, 55)-net over F₅, using

t-expansion [i] based on digital (23, 81, 55)-net over F₅, using
- net from sequence [i] based on digital (23, 54)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₅ with g(F) = 23 and N(F) ≥ 55, using
    - algebraic function fields over â„¤₅ by Niederreiter/Xing [i]

(81−57, 81, 260)-Net in Base 5 — Upper bound on s

There is no (24, 81, 261)-net in base 5, because

1 times m-reduction [i] would yield (24, 80, 261)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 86 402337 817198 697235 824890 727769 985973 413423 408587 431825 > 5⁸⁰ [i]
