Best Known (61−33, 61, s)-Nets in Base 9

(61−33, 61, 78)-Net over F₉ — Constructive and digital

Digital (28, 61, 78)-net over F₉, using

t-expansion [i] based on digital (22, 61, 78)-net over F₉, using
- net from sequence [i] based on digital (22, 77)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 22 and N(F) ≥ 78, using
    - F₃ from the tower of function fields by GarcÃa and Stichtenoth over F₉ [i]

(61−33, 61, 82)-Net in Base 9 — Constructive

(28, 61, 82)-net in base 9, using

      - a function field by SÃ©mirat [i]

(61−33, 61, 110)-Net over F₉ — Digital

Digital (28, 61, 110)-net over F₉, using

t-expansion [i] based on digital (26, 61, 110)-net over F₉, using
- net from sequence [i] based on digital (26, 109)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 26 and N(F) ≥ 110, using
    - a curve from the manYPoints database [i]

(61−33, 61, 3210)-Net in Base 9 — Upper bound on s

There is no (28, 61, 3211)-net in base 9, because

1 times m-reduction [i] would yield (28, 60, 3211)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 1801 252721 701478 128449 378372 429884 582631 073391 071234 457985 > 9⁶⁰ [i]
