MinT - Best Known (247−155, 247, s)-Nets in Base 3

Best Known (247−155, 247, s)-Nets in Base 3

(247−155, 247, 64)-Net over F₃ — Constructive and digital

Digital (92, 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]

(247−155, 247, 96)-Net over F₃ — Digital

Digital (92, 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]

(247−155, 247, 421)-Net in Base 3 — Upper bound on s

There is no (92, 247, 422)-net in base 3, because

1 times m-reduction [i] would yield (92, 246, 422)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2696 701209 089439 934130 067640 751768 113278 532187 439863 800922 055535 410836 074899 061749 640477 834722 740870 275774 884045 064341 > 3²⁴⁶ [i]
