Best Known (42, 143, s)-Nets in Base 8

(42, 143, 98)-Net over F₈ — Constructive and digital

Digital (42, 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]

(42, 143, 129)-Net over F₈ — Digital

Digital (42, 143, 129)-net over F₈, using

t-expansion [i] based on digital (38, 143, 129)-net over F₈, using
- net from sequence [i] based on digital (38, 128)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 38 and N(F) ≥ 129, using
    - a curve from the manYPoints database [i]

(42, 143, 990)-Net in Base 8 — Upper bound on s

There is no (42, 143, 991)-net in base 8, because

1 times m-reduction [i] would yield (42, 142, 991)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 178 562571 410004 803924 337681 042672 899276 617394 535195 622351 169191 392656 588132 757909 778649 009435 731398 919784 716466 653288 427191 057846 > 8¹⁴² [i]
