MinT - Best Known (207−121, 207, s)-Nets in Base 3

Best Known (207−121, 207, s)-Nets in Base 3

(207−121, 207, 61)-Net over F₃ — Constructive and digital

Digital (86, 207, 61)-net over F₃, using

net from sequence [i] based on digital (86, 60)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 60)-sequence over F₉, using
  - s-reduction based on digital (13, 63)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 13 and N(F) ≥ 64, using
      - a function field by GarcÃa and Quoos [i]

(207−121, 207, 84)-Net over F₃ — Digital

Digital (86, 207, 84)-net over F₃, using

t-expansion [i] based on digital (71, 207, 84)-net over F₃, using
- net from sequence [i] based on digital (71, 83)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 71 and N(F) ≥ 84, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(207−121, 207, 447)-Net in Base 3 — Upper bound on s

There is no (86, 207, 448)-net in base 3, because

1 times m-reduction [i] would yield (86, 206, 448)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 212 025635 618501 414430 435607 248662 960896 853200 797823 360053 986790 598163 033235 934823 636227 114376 239617 > 3²⁰⁶ [i]
