Best Known (33−22, 33, s)-Nets in Base 81

(33−22, 33, 172)-Net over F₈₁ — Constructive and digital

Digital (11, 33, 172)-net over F₈₁, using

t-expansion [i] based on digital (7, 33, 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]

(33−22, 33, 244)-Net over F₈₁ — Digital

Digital (11, 33, 244)-net over F₈₁, using

t-expansion [i] based on digital (9, 33, 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]

(33−22, 33, 32606)-Net in Base 81 — Upper bound on s

There is no (11, 33, 32607)-net in base 81, because

the generalized Rao bound for nets shows that 81^mÂ â‰¥ 955 005835 688269 543001 405757 021786 310012 097016 237411 120578 070161 > 81³³ [i]
