Best Known (74, 74+89, s)-Nets in Base 3

(74, 74+89, 56)-Net over F₃ — Constructive and digital

Digital (74, 163, 56)-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 (15, 104, 28)-net over F₃, using
  - net from sequence [i] based on digital (15, 27)-sequence over F₃ (see above)

(74, 74+89, 84)-Net over F₃ — Digital

Digital (74, 163, 84)-net over F₃, using

t-expansion [i] based on digital (71, 163, 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]

(74, 74+89, 450)-Net in Base 3 — Upper bound on s

There is no (74, 163, 451)-net in base 3, because

1 times m-reduction [i] would yield (74, 162, 451)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 201799 099314 888606 764255 364911 028548 895842 702867 499411 491750 783867 992496 227593 > 3¹⁶² [i]
