Best Known (30, 30+81, s)-Nets in Base 9

(30, 30+81, 78)-Net over F₉ — Constructive and digital

Digital (30, 111, 78)-net over F₉, using

t-expansion [i] based on digital (22, 111, 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]

(30, 30+81, 110)-Net over F₉ — Digital

Digital (30, 111, 110)-net over F₉, using

t-expansion [i] based on digital (26, 111, 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]

(30, 30+81, 805)-Net in Base 9 — Upper bound on s

There is no (30, 111, 806)-net in base 9, because

1 times m-reduction [i] would yield (30, 110, 806)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 957 522297 333241 896213 992722 792313 322466 014930 229576 302590 988291 692759 892053 389271 913340 875430 997196 054145 > 9¹¹⁰ [i]
