Best Known (121−90, 121, s)-Nets in Base 9

(121−90, 121, 78)-Net over F₉ — Constructive and digital

Digital (31, 121, 78)-net over F₉, using

t-expansion [i] based on digital (22, 121, 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]

(121−90, 121, 120)-Net over F₉ — Digital

Digital (31, 121, 120)-net over F₉, using

net from sequence [i] based on digital (31, 119)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 31 and N(F) ≥ 120, using
  - a curve from the manYPoints database [i]

(121−90, 121, 783)-Net in Base 9 — Upper bound on s

There is no (31, 121, 784)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 29 900896 238926 644199 299731 107956 993577 029878 662041 000084 700173 171462 191742 269656 419332 092252 140971 753687 635108 760193 > 9¹²¹ [i]
