MinT - Best Known (223−139, 223, s)-Nets in Base 3

Best Known (223−139, 223, s)-Nets in Base 3

(223−139, 223, 59)-Net over F₃ — Constructive and digital

Digital (84, 223, 59)-net over F₃, using

net from sequence [i] based on digital (84, 58)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 58)-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]

(223−139, 223, 84)-Net over F₃ — Digital

Digital (84, 223, 84)-net over F₃, using

t-expansion [i] based on digital (71, 223, 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]

(223−139, 223, 390)-Net in Base 3 — Upper bound on s

There is no (84, 223, 391)-net in base 3, because

1 times m-reduction [i] would yield (84, 222, 391)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 9453 466462 795323 735073 413055 492155 163423 550112 984343 106546 054911 768040 506914 999251 375165 293208 249726 345415 > 3²²² [i]
