MinT - Best Known (220−91, 220, s)-Nets in Base 3

Best Known (220−91, 220, s)-Nets in Base 3

(220−91, 220, 148)-Net over F₃ — Constructive and digital

Digital (129, 220, 148)-net over F₃, using

4 times m-reduction [i] based on digital (129, 224, 148)-net over F₃, using
- trace code for nets [i] based on digital (17, 112, 74)-net over F₉, using
  - net from sequence [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]

(220−91, 220, 185)-Net over F₃ — Digital

Digital (129, 220, 185)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(220−91, 220, 1805)-Net in Base 3 — Upper bound on s

There is no (129, 220, 1806)-net in base 3, because

1 times m-reduction [i] would yield (129, 219, 1806)-net in base 3, but
