Best Known (45, 70, s)-Nets in Base 7

(45, 70, 126)-Net over F₇ — Constructive and digital

Digital (45, 70, 126)-net over F₇, using

(u,Â u+v)-construction [i] based on
1. digital (8, 20, 26)-net over F₇, using
  - (u,Â u+v)-construction [i] based on
    1. digital (1, 7, 13)-net over F₇, using
      - 6 times m-reduction [i] based on digital (1, 13, 13)-net over F₇, using
        a shift-net [i]
    2. digital (1, 13, 13)-net over F₇ (see above)
2. digital (25, 50, 100)-net over F₇, using
  - trace code for nets [i] based on digital (0, 25, 50)-net over F₄₉, using
    - net from sequence [i] based on digital (0, 49)-sequence over F₄₉, using
      - generalized Faure sequence [i]
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄₉ with g(F) = 0 and N(F) ≥ 50, using
        the rational function field F₄₉(x) [i]
      - Niederreiter sequence [i]

(45, 70, 488)-Net over F₇ — Digital

Digital (45, 70, 488)-net over F₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(45, 70, 63748)-Net in Base 7 — Upper bound on s

There is no (45, 70, 63749)-net in base 7, because

1 times m-reduction [i] would yield (45, 69, 63749)-net in base 7, but
- the generalized Rao bound for nets shows that 7^mÂ â‰¥ 20500 838796 912273 670796 700628 374249 580369 847642 783200 784929 > 7⁶⁹ [i]
