MinT - Best Known (239−119, 239, s)-Nets in Base 3

Best Known (239−119, 239, s)-Nets in Base 3

(239−119, 239, 77)-Net over F₃ — Constructive and digital

Digital (120, 239, 77)-net over F₃, using

net from sequence [i] based on digital (120, 76)-sequence over F₃, using
- base reduction for sequences [i] based on digital (22, 76)-sequence over F₉, using
  - s-reduction based on digital (22, 77)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 22 and N(F) ≥ 78, using
      - F₃ from the tower of function fields by GarcÃa and Stichtenoth over F₉ [i]

(239−119, 239, 120)-Net over F₃ — Digital

Digital (120, 239, 120)-net over F₃, using

t-expansion [i] based on digital (113, 239, 120)-net over F₃, using
- net from sequence [i] based on digital (113, 119)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 113 and N(F) ≥ 120, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(239−119, 239, 902)-Net in Base 3 — Upper bound on s

There is no (120, 239, 903)-net in base 3, because

1 times m-reduction [i] would yield (120, 238, 903)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 375327 140055 324956 272654 991468 238029 470234 020698 521255 136395 178328 414756 342006 628006 703000 404634 599064 434495 303467 > 3²³⁸ [i]
