Best Known (128−81, 128, s)-Nets in Base 8

(128−81, 128, 98)-Net over F₈ — Constructive and digital

Digital (47, 128, 98)-net over F₈, using

t-expansion [i] based on digital (37, 128, 98)-net over F₈, using
- net from sequence [i] based on digital (37, 97)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 37 and N(F) ≥ 98, using
    - F₅ from the tower of function fields over F₈ by van der Geer and van der Vlugt [i]

(128−81, 128, 144)-Net over F₈ — Digital

Digital (47, 128, 144)-net over F₈, using

t-expansion [i] based on digital (45, 128, 144)-net over F₈, using
- net from sequence [i] based on digital (45, 143)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 45 and N(F) ≥ 144, using
    - Drinfeld modules of rank 1 [i]

(128−81, 128, 1634)-Net in Base 8 — Upper bound on s

There is no (47, 128, 1635)-net in base 8, because

1 times m-reduction [i] would yield (47, 127, 1635)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 4 984567 917771 672142 932051 652549 477201 122209 218098 871064 553531 302007 021487 359990 288581 956975 867723 680555 705864 846408 > 8¹²⁷ [i]
