(40, 40+55, 81)-Net over F₉ — Constructive and digital

Digital (40, 95, 81)-net over F₉, using

t-expansion [i] based on digital (32, 95, 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]

      - a function field by SÃ©mirat [i]

(40, 40+55, 140)-Net over F₉ — Digital

Digital (40, 95, 140)-net over F₉, using

t-expansion [i] based on digital (39, 95, 140)-net over F₉, using
- net from sequence [i] based on digital (39, 139)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 39 and N(F) ≥ 140, using

(40, 40+55, 2851)-Net in Base 9 — Upper bound on s

There is no (40, 95, 2852)-net in base 9, because

1 times m-reduction [i] would yield (40, 94, 2852)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 504084 804307 543320 889140 080905 031698 148857 146322 545826 095531 995017 770641 993473 595384 313825 > 9⁹⁴ [i]
