MinT - Best Known (208−45, 208, s)-Nets in Base 3

Best Known (208−45, 208, s)-Nets in Base 3

(208−45, 208, 688)-Net over F₃ — Constructive and digital

Digital (163, 208, 688)-net over F₃, using

trace code for nets [i] based on digital (7, 52, 172)-net over F₈₁, using
- net from sequence [i] based on digital (7, 171)-sequence over F₈₁, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 7 and N(F) ≥ 172, using
    - a function field by SÃ©mirat [i]

(208−45, 208, 1575)-Net over F₃ — Digital

Digital (163, 208, 1575)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(208−45, 208, 139647)-Net in Base 3 — Upper bound on s

There is no (163, 208, 139648)-net in base 3, because

1 times m-reduction [i] would yield (163, 207, 139648)-net in base 3, but
