Best Known (25, 25+121, s)-Nets in Base 9

(25, 25+121, 78)-Net over F₉ — Constructive and digital

Digital (25, 146, 78)-net over F₉, using

t-expansion [i] based on digital (22, 146, 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]

(25, 25+121, 96)-Net over F₉ — Digital

Digital (25, 146, 96)-net over F₉, using

net from sequence [i] based on digital (25, 95)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 25 and N(F) ≥ 96, using
  - a curve from the manYPoints database [i]

(25, 25+121, 550)-Net in Base 9 — Upper bound on s

There is no (25, 146, 551)-net in base 9, because

1 times m-reduction [i] would yield (25, 145, 551)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 2 503132 976933 535276 523506 441303 219479 625421 553686 231794 328197 229963 637075 491022 938675 046311 768246 343950 652025 680564 786056 606307 977523 562273 > 9¹⁴⁵ [i]
