MinT - Best Known (237−133, 237, s)-Nets in Base 3

Best Known (237−133, 237, s)-Nets in Base 3

(237−133, 237, 71)-Net over F₃ — Constructive and digital

Digital (104, 237, 71)-net over F₃, using

net from sequence [i] based on digital (104, 70)-sequence over F₃, using
- base reduction for sequences [i] based on digital (17, 70)-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]

(237−133, 237, 104)-Net over F₃ — Digital

Digital (104, 237, 104)-net over F₃, using

t-expansion [i] based on digital (102, 237, 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]

(237−133, 237, 582)-Net in Base 3 — Upper bound on s

There is no (104, 237, 583)-net in base 3, because

1 times m-reduction [i] would yield (104, 236, 583)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 39997 460346 444183 189954 927883 737655 515454 093252 816609 993527 293869 035637 471098 425232 811857 531070 809271 897924 512909 > 3²³⁶ [i]
