Best Known (47−36, 47, s)-Nets in Base 81

(47−36, 47, 172)-Net over F₈₁ — Constructive and digital

Digital (11, 47, 172)-net over F₈₁, using

t-expansion [i] based on digital (7, 47, 172)-net over F₈₁, using
- net from sequence [i] based on digital (7, 171)-sequence over F₈₁, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 7 and N(F) ≥ 172, using
    - a function field by SÃ©mirat [i]

(47−36, 47, 244)-Net over F₈₁ — Digital

Digital (11, 47, 244)-net over F₈₁, using

t-expansion [i] based on digital (9, 47, 244)-net over F₈₁, using
- net from sequence [i] based on digital (9, 243)-sequence over F₈₁, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 9 and N(F) ≥ 244, using
    - K_1,1 from the tower of function fields by Niederreiter and Xing based on the tower by GarcÃa and Stichtenoth over F₈₁ [i]

(47−36, 47, 9075)-Net in Base 81 — Upper bound on s

There is no (11, 47, 9076)-net in base 81, because

the generalized Rao bound for nets shows that 81^mÂ â‰¥ 499907 239829 566018 414540 041633 357789 999401 469478 193825 823437 928206 303823 177898 606921 600641 > 81⁴⁷ [i]
