Best Known (191−47, 191, s)-Nets in Base 3

(191−47, 191, 328)-Net over F₃ — Constructive and digital

Digital (144, 191, 328)-net over F₃, using

1 times m-reduction [i] based on digital (144, 192, 328)-net over F₃, using
- trace code for nets [i] based on digital (0, 48, 82)-net over F₈₁, using
  - net from sequence [i] based on digital (0, 81)-sequence over F₈₁, using
    - generalized Faure sequence [i]
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 0 and N(F) ≥ 82, using
      - the rational function field F₈₁(x) [i]
    - Niederreiter sequence [i]

(191−47, 191, 872)-Net over F₃ — Digital

Digital (144, 191, 872)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(191−47, 191, 41174)-Net in Base 3 — Upper bound on s

There is no (144, 191, 41175)-net in base 3, because

1 times m-reduction [i] would yield (144, 190, 41175)-net in base 3, but
