MinT - Best Known (206−127, 206, s)-Nets in Base 3

Best Known (206−127, 206, s)-Nets in Base 3

(206−127, 206, 54)-Net over F₃ — Constructive and digital

Digital (79, 206, 54)-net over F₃, using

net from sequence [i] based on digital (79, 53)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 53)-sequence over F₉, using
  - s-reduction based on digital (13, 63)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 13 and N(F) ≥ 64, using
      - a function field by GarcÃa and Quoos [i]

(206−127, 206, 84)-Net over F₃ — Digital

Digital (79, 206, 84)-net over F₃, using

t-expansion [i] based on digital (71, 206, 84)-net over F₃, using
- net from sequence [i] based on digital (71, 83)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 71 and N(F) ≥ 84, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(206−127, 206, 374)-Net in Base 3 — Upper bound on s

There is no (79, 206, 375)-net in base 3, because

1 times m-reduction [i] would yield (79, 205, 375)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 67 742851 339421 010197 903103 313039 711437 125894 171660 896839 967582 542224 570952 946244 423328 820521 672291 > 3²⁰⁵ [i]
