MinT - Best Known (218−113, 218, s)-Nets in Base 3

Best Known (218−113, 218, s)-Nets in Base 3

(218−113, 218, 72)-Net over F₃ — Constructive and digital

Digital (105, 218, 72)-net over F₃, using

net from sequence [i] based on digital (105, 71)-sequence over F₃, using
- base reduction for sequences [i] based on digital (17, 71)-sequence over F₉, using
  - s-reduction 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]

(218−113, 218, 104)-Net over F₃ — Digital

Digital (105, 218, 104)-net over F₃, using

t-expansion [i] based on digital (102, 218, 104)-net over F₃, using
- net from sequence [i] based on digital (102, 103)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 102 and N(F) ≥ 104, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(218−113, 218, 712)-Net in Base 3 — Upper bound on s

There is no (105, 218, 713)-net in base 3, because

1 times m-reduction [i] would yield (105, 217, 713)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 35 550849 174398 574782 022259 475169 499556 820467 767346 157359 227283 146473 247990 319099 438545 460969 043273 153633 > 3²¹⁷ [i]
