Best Known (63, 108, s)-Nets in Base 9

(63, 108, 344)-Net over F₉ — Constructive and digital

Digital (63, 108, 344)-net over F₉, using

4 times m-reduction [i] based on digital (63, 112, 344)-net over F₉, using
- trace code for nets [i] based on digital (7, 56, 172)-net over F₈₁, using
  - net from sequence [i] based on digital (7, 171)-sequence over F₈₁, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 7 and N(F) ≥ 172, using
      - a function field by SÃ©mirat [i]

(63, 108, 488)-Net over F₉ — Digital

Digital (63, 108, 488)-net over F₉, using

trace code for nets [i] based on digital (9, 54, 244)-net over F₈₁, using
- net from sequence [i] based on digital (9, 243)-sequence over F₈₁, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 9 and N(F) ≥ 244, using
    - K_1,1 from the tower of function fields by Niederreiter and Xing based on the tower by GarcÃa and Stichtenoth over F₈₁ [i]

(63, 108, 49514)-Net in Base 9 — Upper bound on s

There is no (63, 108, 49515)-net in base 9, because

1 times m-reduction [i] would yield (63, 107, 49515)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 1 270511 341258 754570 384791 089242 779630 230280 230353 738225 927320 941342 489574 934082 963019 911534 993450 150161 > 9¹⁰⁷ [i]
