Best Known (11, 11+38, s)-Nets in Base 81

(11, 11+38, 172)-Net over F₈₁ — Constructive and digital

Digital (11, 49, 172)-net over F₈₁, using

t-expansion [i] based on digital (7, 49, 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]

(11, 11+38, 244)-Net over F₈₁ — Digital

    - K_1,1 from the tower of function fields by Niederreiter and Xing based on the tower by GarcÃa and Stichtenoth over F₈₁ [i]

(11, 11+38, 8270)-Net in Base 81 — Upper bound on s

There is no (11, 49, 8271)-net in base 81, because

the generalized Rao bound for nets shows that 81^mÂ â‰¥ 3284 173911 287198 317733 082643 098084 709873 814423 326260 786391 085247 580928 477737 439273 341316 226321 > 81⁴⁹ [i]
