Best Known (52, 52+81, s)-Nets in Base 8

(52, 52+81, 98)-Net over F₈ — Constructive and digital

Digital (52, 133, 98)-net over F₈, using

t-expansion [i] based on digital (37, 133, 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]

(52, 52+81, 144)-Net over F₈ — Digital

Digital (52, 133, 144)-net over F₈, using

t-expansion [i] based on digital (45, 133, 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]

(52, 52+81, 2127)-Net in Base 8 — Upper bound on s

There is no (52, 133, 2128)-net in base 8, because

1 times m-reduction [i] would yield (52, 132, 2128)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 164075 361732 479560 430939 557531 695689 251859 312776 344159 857532 991620 229506 332153 962842 457921 758332 680401 827790 158670 581466 > 8¹³² [i]
