Best Known (9, 51, s)-Nets in Base 81

(9, 51, 172)-Net over F₈₁ — Constructive and digital

Digital (9, 51, 172)-net over F₈₁, using

t-expansion [i] based on digital (7, 51, 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]

(9, 51, 244)-Net over F₈₁ — Digital

Digital (9, 51, 244)-net over F₈₁, using

net from sequence [i] based on digital (9, 243)-sequence over F₈₁, 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]

(9, 51, 4670)-Net in Base 81 — Upper bound on s

There is no (9, 51, 4671)-net in base 81, because

the generalized Rao bound for nets shows that 81^mÂ â‰¥ 21 585393 467128 011317 777045 608228 714752 631343 126090 239460 911857 564307 808393 898240 405955 067426 471281 > 81⁵¹ [i]
