Best Known (173−97, 173, s)-Nets in Base 3

(173−97, 173, 52)-Net over F₃ — Constructive and digital

Digital (76, 173, 52)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (13, 61, 24)-net over F₃, using
  - net from sequence [i] based on digital (13, 23)-sequence over F₃, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 13 and N(F) ≥ 24, using
      - a function field by SÃ©mirat [i]
2. digital (15, 112, 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]

(173−97, 173, 84)-Net over F₃ — Digital

Digital (76, 173, 84)-net over F₃, using

t-expansion [i] based on digital (71, 173, 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]

(173−97, 173, 434)-Net in Base 3 — Upper bound on s

There is no (76, 173, 435)-net in base 3, because

1 times m-reduction [i] would yield (76, 172, 435)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 12106 030479 355662 037223 921066 899642 010964 227394 621478 321388 667168 693602 690170 098849 > 3¹⁷² [i]
