MinT - Best Known (220−117, 220, s)-Nets in Base 3

Best Known (220−117, 220, s)-Nets in Base 3

(220−117, 220, 70)-Net over F₃ — Constructive and digital

Digital (103, 220, 70)-net over F₃, using

net from sequence [i] based on digital (103, 69)-sequence over F₃, using
- base reduction for sequences [i] based on digital (17, 69)-sequence over F₉, using
  - s-reduction based on digital (17, 73)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 17 and N(F) ≥ 74, using
      - a function field by GarcÃa and Quoos [i]

(220−117, 220, 104)-Net over F₃ — Digital

Digital (103, 220, 104)-net over F₃, using

t-expansion [i] based on digital (102, 220, 104)-net over F₃, using
- net from sequence [i] based on digital (102, 103)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 102 and N(F) ≥ 104, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(220−117, 220, 655)-Net in Base 3 — Upper bound on s

There is no (103, 220, 656)-net in base 3, because

1 times m-reduction [i] would yield (103, 219, 656)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 331 031390 358233 740071 003813 234871 730060 069316 998176 085005 648511 083200 196272 437485 760392 708355 625714 173025 > 3²¹⁹ [i]
