MinT - Best Known (243−143, 243, s)-Nets in Base 3

Best Known (243−143, 243, s)-Nets in Base 3

(243−143, 243, 67)-Net over F₃ — Constructive and digital

Digital (100, 243, 67)-net over F₃, using

net from sequence [i] based on digital (100, 66)-sequence over F₃, using
- base reduction for sequences [i] based on digital (17, 66)-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]

(243−143, 243, 96)-Net over F₃ — Digital

Digital (100, 243, 96)-net over F₃, using

t-expansion [i] based on digital (89, 243, 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]

(243−143, 243, 509)-Net in Base 3 — Upper bound on s

There is no (100, 243, 510)-net in base 3, because

1 times m-reduction [i] would yield (100, 242, 510)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 31 206966 760572 465501 139161 173277 758484 870877 892490 627515 274363 617541 982574 937115 969026 108319 688770 001161 913822 272953 > 3²⁴² [i]
