Best Known (56, 56+115, s)-Nets in Base 8

(56, 56+115, 98)-Net over F₈ — Constructive and digital

Digital (56, 171, 98)-net over F₈, using

t-expansion [i] based on digital (37, 171, 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]

(56, 56+115, 144)-Net over F₈ — Digital

Digital (56, 171, 144)-net over F₈, using

t-expansion [i] based on digital (45, 171, 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]

(56, 56+115, 1521)-Net in Base 8 — Upper bound on s

There is no (56, 171, 1522)-net in base 8, because

1 times m-reduction [i] would yield (56, 170, 1522)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 3447 155561 441500 057848 880990 445065 452153 905391 949938 799359 289126 838657 743110 590868 438527 604518 546894 321837 842571 091528 131659 654763 599292 849011 901545 889624 > 8¹⁷⁰ [i]
