Best Known (121−78, 121, s)-Nets in Base 9

(121−78, 121, 81)-Net over F₉ — Constructive and digital

Digital (43, 121, 81)-net over F₉, using

t-expansion [i] based on digital (32, 121, 81)-net over F₉, using
- net from sequence [i] based on digital (32, 80)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 32 and N(F) ≥ 81, using
    - F₄ from the tower of function fields by Bezerra and GarcÃa over F₉ [i]

(121−78, 121, 147)-Net over F₉ — Digital

Digital (43, 121, 147)-net over F₉, using

net from sequence [i] based on digital (43, 146)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 43 and N(F) ≥ 147, using

(121−78, 121, 1733)-Net in Base 9 — Upper bound on s

There is no (43, 121, 1734)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 29 143559 758093 463725 269356 865892 887025 521167 395116 406235 475824 072393 870966 003377 699598 025909 901648 238331 246286 519185 > 9¹²¹ [i]
