MinT - Best Known (218−135, 218, s)-Nets in Base 3

Best Known (218−135, 218, s)-Nets in Base 3

(218−135, 218, 58)-Net over F₃ — Constructive and digital

Digital (83, 218, 58)-net over F₃, using

net from sequence [i] based on digital (83, 57)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 57)-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]

(218−135, 218, 84)-Net over F₃ — Digital

Digital (83, 218, 84)-net over F₃, using

t-expansion [i] based on digital (71, 218, 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]

(218−135, 218, 389)-Net in Base 3 — Upper bound on s

There is no (83, 218, 390)-net in base 3, because

1 times m-reduction [i] would yield (83, 217, 390)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 35 346389 524329 836057 568606 784984 705164 467637 721725 601984 569868 354113 398351 788001 454112 560804 753823 550049 > 3²¹⁷ [i]
