Best Known (27, 27+89, s)-Nets in Base 9

(27, 27+89, 78)-Net over F₉ — Constructive and digital

Digital (27, 116, 78)-net over F₉, using

t-expansion [i] based on digital (22, 116, 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]

(27, 27+89, 110)-Net over F₉ — Digital

Digital (27, 116, 110)-net over F₉, using

t-expansion [i] based on digital (26, 116, 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]

(27, 27+89, 646)-Net in Base 9 — Upper bound on s

There is no (27, 116, 647)-net in base 9, because

1 times m-reduction [i] would yield (27, 115, 647)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 58 015278 721040 979113 509144 553808 062581 193953 533126 039046 239760 443475 961982 069149 662198 163082 284011 638409 066401 > 9¹¹⁵ [i]
