Best Known (69, 147, s)-Nets in Base 3

(69, 147, 56)-Net over F₃ — Constructive and digital

Digital (69, 147, 56)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (15, 54, 28)-net over F₃, using
  - net from sequence [i] based on digital (15, 27)-sequence over F₃, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 15 and N(F) ≥ 28, using
      - an explicitly constructive algebraic function field [i]
2. digital (15, 93, 28)-net over F₃, using
  - net from sequence [i] based on digital (15, 27)-sequence over F₃ (see above)
