MinT - Best Known (226−117, 226, s)-Nets in Base 3

Best Known (226−117, 226, s)-Nets in Base 3

(226−117, 226, 74)-Net over F₃ — Constructive and digital

Digital (109, 226, 74)-net over F₃, using

t-expansion [i] based on digital (107, 226, 74)-net over F₃, using
- net from sequence [i] based on digital (107, 73)-sequence over F₃, using
  - base reduction for sequences [i] 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]

(226−117, 226, 104)-Net over F₃ — Digital

Digital (109, 226, 104)-net over F₃, using

t-expansion [i] based on digital (102, 226, 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]

(226−117, 226, 740)-Net in Base 3 — Upper bound on s

There is no (109, 226, 741)-net in base 3, because

1 times m-reduction [i] would yield (109, 225, 741)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 233334 263665 590658 386208 903520 348692 014756 426505 194409 255894 335615 432043 897433 285571 938239 125159 534207 927153 > 3²²⁵ [i]
