MinT - Best Known (143−55, 143, s)-Nets in Base 4

Best Known (143−55, 143, s)-Nets in Base 4

(143−55, 143, 130)-Net over F₄ — Constructive and digital

Digital (88, 143, 130)-net over F₄, using

21 times m-reduction [i] based on digital (88, 164, 130)-net over F₄, using
- trace code for nets [i] based on digital (6, 82, 65)-net over F₁₆, using
  - net from sequence [i] based on digital (6, 64)-sequence over F₁₆, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 6 and N(F) ≥ 65, using
      - the Hermitian function field over F₁₆ [i]

(143−55, 143, 251)-Net over F₄ — Digital

Digital (88, 143, 251)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(143−55, 143, 5319)-Net in Base 4 — Upper bound on s

There is no (88, 143, 5320)-net in base 4, because

1 times m-reduction [i] would yield (88, 142, 5320)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 31 132897 810764 268885 568366 796844 385629 241883 234416 169048 833914 097284 380527 040806 246440 > 4¹⁴² [i]
