MinT - Best Known (43−33, 43, s)-Nets in Base 81

Best Known (43−33, 43, s)-Nets in Base 81

(43−33, 43, 172)-Net over F₈₁ — Constructive and digital

Digital (10, 43, 172)-net over F₈₁, using

t-expansion [i] based on digital (7, 43, 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]

(43−33, 43, 244)-Net over F₈₁ — Digital

Digital (10, 43, 244)-net over F₈₁, using

t-expansion [i] based on digital (9, 43, 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]

(43−33, 43, 8686)-Net in Base 81 — Upper bound on s

There is no (10, 43, 8687)-net in base 81, because

1 times m-reduction [i] would yield (10, 42, 8687)-net in base 81, but
- the generalized Rao bound for nets shows that 81^mÂ â‰¥ 143 513484 991234 144701 089698 273517 111987 687601 771599 508915 799157 191689 933800 303361 > 81⁴² [i]
