MinT - Best Known (246−129, 246, s)-Nets in Base 3

Best Known (246−129, 246, s)-Nets in Base 3

(246−129, 246, 74)-Net over F₃ — Constructive and digital

Digital (117, 246, 74)-net over F₃, using

t-expansion [i] based on digital (107, 246, 74)-net over F₃, using
- net from sequence [i] based on digital (107, 73)-sequence over F₃, using
  - base reduction for sequences [i] 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]

(246−129, 246, 120)-Net over F₃ — Digital

Digital (117, 246, 120)-net over F₃, using

t-expansion [i] based on digital (113, 246, 120)-net over F₃, using
- net from sequence [i] based on digital (113, 119)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 113 and N(F) ≥ 120, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(246−129, 246, 765)-Net in Base 3 — Upper bound on s

There is no (117, 246, 766)-net in base 3, because

1 times m-reduction [i] would yield (117, 245, 766)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 796 869390 689901 860428 090847 345752 048097 219225 157775 419605 600423 575378 456099 081448 713404 806122 933259 310826 938985 127553 > 3²⁴⁵ [i]
