MinT - Best Known (138−49, 138, s)-Nets in Base 3

Best Known (138−49, 138, s)-Nets in Base 3

(138−49, 138, 148)-Net over F₃ — Constructive and digital

Digital (89, 138, 148)-net over F₃, using

6 times m-reduction [i] based on digital (89, 144, 148)-net over F₃, using
- trace code for nets [i] based on digital (17, 72, 74)-net over F₉, using
  - net from sequence [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]

(138−49, 138, 193)-Net over F₃ — Digital

Digital (89, 138, 193)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(138−49, 138, 2570)-Net in Base 3 — Upper bound on s

There is no (89, 138, 2571)-net in base 3, because

1 times m-reduction [i] would yield (89, 137, 2571)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 233854 959525 429955 584777 156472 093807 316837 364525 340204 206774 981201 > 3¹³⁷ [i]
