MinT - Best Known (249−143, 249, s)-Nets in Base 3

Best Known (249−143, 249, s)-Nets in Base 3

(249−143, 249, 73)-Net over F₃ — Constructive and digital

Digital (106, 249, 73)-net over F₃, using

net from sequence [i] based on digital (106, 72)-sequence over F₃, using
- base reduction for sequences [i] based on digital (17, 72)-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]

(249−143, 249, 104)-Net over F₃ — Digital

Digital (106, 249, 104)-net over F₃, using

t-expansion [i] based on digital (102, 249, 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]

(249−143, 249, 565)-Net in Base 3 — Upper bound on s

There is no (106, 249, 566)-net in base 3, because

1 times m-reduction [i] would yield (106, 248, 566)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 23095 039642 167500 945962 066900 207817 470433 316485 300913 447526 922158 545862 588950 848891 349982 866239 038280 351269 292841 553113 > 3²⁴⁸ [i]
