Best Known (138−65, 138, s)-Nets in Base 3

(138−65, 138, 64)-Net over F₃ — Constructive and digital

Digital (73, 138, 64)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (15, 47, 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, 91, 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]

(138−65, 138, 86)-Net over F₃ — Digital

Digital (73, 138, 86)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(138−65, 138, 674)-Net in Base 3 — Upper bound on s

There is no (73, 138, 675)-net in base 3, because

1 times m-reduction [i] would yield (73, 137, 675)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 236102 613265 394384 296290 894956 565886 268311 676296 130971 747628 594625 > 3¹³⁷ [i]
