MinT - Best Known (231−135, 231, s)-Nets in Base 3

Best Known (231−135, 231, s)-Nets in Base 3

(231−135, 231, 64)-Net over F₃ — Constructive and digital

Digital (96, 231, 64)-net over F₃, using

t-expansion [i] based on digital (89, 231, 64)-net over F₃, using
- net from sequence [i] based on digital (89, 63)-sequence over F₃, using
  - base reduction for sequences [i] 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]

(231−135, 231, 96)-Net over F₃ — Digital

Digital (96, 231, 96)-net over F₃, using

t-expansion [i] based on digital (89, 231, 96)-net over F₃, using
- net from sequence [i] based on digital (89, 95)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 89 and N(F) ≥ 96, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(231−135, 231, 496)-Net in Base 3 — Upper bound on s

There is no (96, 231, 497)-net in base 3, because

1 times m-reduction [i] would yield (96, 230, 497)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 57 157489 923637 471953 691514 981996 699867 928210 238080 931538 387861 918736 008452 047536 298120 388790 946474 160568 434011 > 3²³⁰ [i]
