Best Known (170−85, 170, s)-Nets in Base 3

(170−85, 170, 65)-Net over F₃ — Constructive and digital

Digital (85, 170, 65)-net over F₃, using

1 times m-reduction [i] based on digital (85, 171, 65)-net over F₃, using
- (u,Â u+v)-construction [i] based on
  1. digital (15, 58, 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, 113, 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]

(170−85, 170, 87)-Net over F₃ — Digital

Digital (85, 170, 87)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(170−85, 170, 645)-Net in Base 3 — Upper bound on s

There is no (85, 170, 646)-net in base 3, because

1 times m-reduction [i] would yield (85, 169, 646)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 430 660110 740578 807769 243923 393979 344777 382141 593995 408187 527535 403898 173606 109757 > 3¹⁶⁹ [i]
