Best Known (174−89, 174, s)-Nets in Base 3

(174−89, 174, 64)-Net over F₃ — Constructive and digital

Digital (85, 174, 64)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (15, 59, 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 (26, 115, 36)-net over F₃, using
  - net from sequence [i] based on digital (26, 35)-sequence over F₃, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 26 and N(F) ≥ 36, using
      - an explicitly constructive algebraic function field [i]

(174−89, 174, 84)-Net over F₃ — Digital

Digital (85, 174, 84)-net over F₃, using

t-expansion [i] based on digital (71, 174, 84)-net over F₃, using
- net from sequence [i] based on digital (71, 83)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 71 and N(F) ≥ 84, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(174−89, 174, 606)-Net in Base 3 — Upper bound on s

There is no (85, 174, 607)-net in base 3, because

1 times m-reduction [i] would yield (85, 173, 607)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 37078 673224 022113 696974 104716 286807 797594 337052 204750 316598 350290 026391 546516 401577 > 3¹⁷³ [i]
