MinT - Best Known (224−119, 224, s)-Nets in Base 3

Best Known (224−119, 224, s)-Nets in Base 3

(224−119, 224, 72)-Net over F₃ — Constructive and digital

Digital (105, 224, 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]

(224−119, 224, 104)-Net over F₃ — Digital

Digital (105, 224, 104)-net over F₃, using

t-expansion [i] based on digital (102, 224, 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]

(224−119, 224, 668)-Net in Base 3 — Upper bound on s

There is no (105, 224, 669)-net in base 3, because

1 times m-reduction [i] would yield (105, 223, 669)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 25147 951702 152525 279789 548470 574913 935949 748610 416511 276032 960573 373430 295396 223051 269615 563182 937053 877867 > 3²²³ [i]
