MinT - Best Known (250−151, 250, s)-Nets in Base 3

Best Known (250−151, 250, s)-Nets in Base 3

(250−151, 250, 66)-Net over F₃ — Constructive and digital

Digital (99, 250, 66)-net over F₃, using

net from sequence [i] based on digital (99, 65)-sequence over F₃, using
- base reduction for sequences [i] based on digital (17, 65)-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]

(250−151, 250, 96)-Net over F₃ — Digital

Digital (99, 250, 96)-net over F₃, using

t-expansion [i] based on digital (89, 250, 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]

(250−151, 250, 480)-Net in Base 3 — Upper bound on s

There is no (99, 250, 481)-net in base 3, because

1 times m-reduction [i] would yield (99, 249, 481)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 63712 038468 409572 811557 405161 915137 816567 585880 461335 151184 504796 918980 406876 760870 307664 503309 748109 176757 930085 965691 > 3²⁴⁹ [i]
