Best Known (142−97, 142, s)-Nets in Base 8

(142−97, 142, 98)-Net over F₈ — Constructive and digital

Digital (45, 142, 98)-net over F₈, using

t-expansion [i] based on digital (37, 142, 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]

(142−97, 142, 144)-Net over F₈ — Digital

Digital (45, 142, 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]

(142−97, 142, 1173)-Net in Base 8 — Upper bound on s

There is no (45, 142, 1174)-net in base 8, because

1 times m-reduction [i] would yield (45, 141, 1174)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 22 032639 670623 189522 759167 955449 513665 032047 684897 077080 164032 108857 126096 574373 108157 754654 629266 817471 307187 790719 730701 459700 > 8¹⁴¹ [i]
