MinT - Best Known (20, 57, s)-Nets in Base 8

Best Known (20, 57, s)-Nets in Base 8

(20, 57, 65)-Net over F₈ — Constructive and digital

Digital (20, 57, 65)-net over F₈, using

t-expansion [i] based on digital (14, 57, 65)-net over F₈, using
- net from sequence [i] based on digital (14, 64)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 14 and N(F) ≥ 65, using
    - the Suzuki function field over F₈ [i]

(20, 57, 76)-Net over F₈ — Digital

Digital (20, 57, 76)-net over F₈, using

net from sequence [i] based on digital (20, 75)-sequence over F₈, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 20 and N(F) ≥ 76, using
  - a curve from the manYPoints database [i]

(20, 57, 685)-Net in Base 8 — Upper bound on s

There is no (20, 57, 686)-net in base 8, because

1 times m-reduction [i] would yield (20, 56, 686)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 383 530777 269070 843824 084072 653699 375046 856950 948332 > 8⁵⁶ [i]
