MinT - Best Known (205−65, 205, s)-Nets in Base 3

Best Known (205−65, 205, s)-Nets in Base 3

(205−65, 205, 167)-Net over F₃ — Constructive and digital

Digital (140, 205, 167)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (9, 41, 19)-net over F₃, using
  - net from sequence [i] based on digital (9, 18)-sequence over F₃, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 9 and N(F) ≥ 19, using
      - an explicitly constructive algebraic function field [i]
2. digital (99, 164, 148)-net over F₃, using
  - trace code for nets [i] based on digital (17, 82, 74)-net over F₉, using
    - net from sequence [i] based on digital (17, 73)-sequence over F₉, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 17 and N(F) ≥ 74, using
        a function field by GarcÃa and Quoos [i]

(205−65, 205, 381)-Net over F₃ — Digital

Digital (140, 205, 381)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(205−65, 205, 7007)-Net in Base 3 — Upper bound on s

There is no (140, 205, 7008)-net in base 3, because

1 times m-reduction [i] would yield (140, 204, 7008)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21 577948 494099 555626 698680 202373 672505 218009 976601 527832 492376 603459 298896 756683 818001 534823 952385 > 3²⁰⁴ [i]
