Best Known (187−97, 187, s)-Nets in Base 3

(187−97, 187, 65)-Net over F₃ — Constructive and digital

Digital (90, 187, 65)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (15, 63, 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 (27, 124, 37)-net over F₃, using
  - net from sequence [i] based on digital (27, 36)-sequence over F₃, using
    - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₃ with g(F)Â =Â 26, N(F)Â =Â 36, and 1 place with degree 2 [i] based on function field F/F₃ with g(F) = 26 and N(F) ≥ 36, using an explicitly constructive algebraic function field [i]

(187−97, 187, 96)-Net over F₃ — Digital

Digital (90, 187, 96)-net over F₃, using

t-expansion [i] based on digital (89, 187, 96)-net over F₃, using
- net from sequence [i] based on digital (89, 95)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 89 and N(F) ≥ 96, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(187−97, 187, 615)-Net in Base 3 — Upper bound on s

There is no (90, 187, 616)-net in base 3, because

1 times m-reduction [i] would yield (90, 186, 616)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 57662 317388 983941 205658 097252 725880 269868 916762 839375 606994 913572 440381 675511 002346 122241 > 3¹⁸⁶ [i]
