Best Known (81, 81+129, s)-Nets in Base 3

(81, 81+129, 56)-Net over F₃ — Constructive and digital

Digital (81, 210, 56)-net over F₃, using

net from sequence [i] based on digital (81, 55)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 55)-sequence over F₉, using
  - s-reduction based on digital (13, 63)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 13 and N(F) ≥ 64, using
      - a function field by GarcÃa and Quoos [i]

(81, 81+129, 84)-Net over F₃ — Digital

Digital (81, 210, 84)-net over F₃, using

t-expansion [i] based on digital (71, 210, 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]

(81, 81+129, 385)-Net in Base 3 — Upper bound on s

There is no (81, 210, 386)-net in base 3, because

1 times m-reduction [i] would yield (81, 209, 386)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 5249 686870 016214 950023 743255 119703 600525 295857 021672 784752 477175 428275 858584 433157 562995 806809 772673 > 3²⁰⁹ [i]
