Best Known (48, 121, s)-Nets in Base 9

(48, 121, 81)-Net over F₉ — Constructive and digital

Digital (48, 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]

(48, 121, 82)-Net in Base 9 — Constructive

(48, 121, 82)-net in base 9, using

  - net from sequence [i] based on digital (7, 81)-sequence over F₂₇, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₇ with g(F) = 7 and N(F) ≥ 82, using
      - a function field by SÃ©mirat [i]

(48, 121, 163)-Net over F₉ — Digital

Digital (48, 121, 163)-net over F₉, using

net from sequence [i] based on digital (48, 162)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 48 and N(F) ≥ 163, using
  - Drinfeld modules of rank 1 [i]

(48, 121, 2684)-Net in Base 9 — Upper bound on s

There is no (48, 121, 2685)-net in base 9, because

1 times m-reduction [i] would yield (48, 120, 2685)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3 235775 754091 184229 342843 401262 643206 733417 841305 501326 387003 591185 140440 728530 640809 893000 871579 644448 234718 330145 > 9¹²⁰ [i]
