Best Known (143−85, 143, s)-Nets in Base 8

(143−85, 143, 98)-Net over F₈ — Constructive and digital

Digital (58, 143, 98)-net over F₈, using

t-expansion [i] based on digital (37, 143, 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]

(143−85, 143, 144)-Net over F₈ — Digital

Digital (58, 143, 144)-net over F₈, using

t-expansion [i] based on digital (45, 143, 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]

(143−85, 143, 2640)-Net in Base 8 — Upper bound on s

There is no (58, 143, 2641)-net in base 8, because

1 times m-reduction [i] would yield (58, 142, 2641)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 174 694431 545998 361289 038636 817753 745033 225814 940929 550293 239313 840974 967509 296274 685561 050566 279377 348599 561359 284447 521224 193200 > 8¹⁴² [i]
