MinT - Best Known (247−151, 247, s)-Nets in Base 3

Best Known (247−151, 247, s)-Nets in Base 3

(247−151, 247, 64)-Net over F₃ — Constructive and digital

Digital (96, 247, 64)-net over F₃, using

t-expansion [i] based on digital (89, 247, 64)-net over F₃, using
- net from sequence [i] based on digital (89, 63)-sequence over F₃, using
  - base reduction for sequences [i] 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]

(247−151, 247, 96)-Net over F₃ — Digital

Digital (96, 247, 96)-net over F₃, using

t-expansion [i] based on digital (89, 247, 96)-net over F₃, using
- net from sequence [i] based on digital (89, 95)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 89 and N(F) ≥ 96, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(247−151, 247, 457)-Net in Base 3 — Upper bound on s

There is no (96, 247, 458)-net in base 3, because

1 times m-reduction [i] would yield (96, 246, 458)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2553 377965 205780 129442 509351 883495 021105 800939 691524 310465 326017 526451 944795 149786 582699 137948 535821 619783 036168 281825 > 3²⁴⁶ [i]
