MinT - Best Known (203−123, 203, s)-Nets in Base 3

Best Known (203−123, 203, s)-Nets in Base 3

(203−123, 203, 55)-Net over F₃ — Constructive and digital

Digital (80, 203, 55)-net over F₃, using

net from sequence [i] based on digital (80, 54)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 54)-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]

(203−123, 203, 84)-Net over F₃ — Digital

Digital (80, 203, 84)-net over F₃, using

t-expansion [i] based on digital (71, 203, 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]

(203−123, 203, 390)-Net in Base 3 — Upper bound on s

There is no (80, 203, 391)-net in base 3, because

1 times m-reduction [i] would yield (80, 202, 391)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2 539840 346907 738830 127526 316498 299384 255842 009340 326432 967883 422615 762195 448183 960910 149162 716119 > 3²⁰² [i]
