MinT - Best Known (143, 218, s)-Nets in Base 2

Best Known (143, 218, s)-Nets in Base 2

(143, 218, 112)-Net over F₂ — Constructive and digital

Digital (143, 218, 112)-net over F₂, using

2 times m-reduction [i] based on digital (143, 220, 112)-net over F₂, using
- trace code for nets [i] based on digital (33, 110, 56)-net over F₄, using
  - net from sequence [i] based on digital (33, 55)-sequence over F₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 33 and N(F) ≥ 56, using
      - F₅ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(143, 218, 140)-Net over F₂ — Digital

Digital (143, 218, 140)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(143, 218, 800)-Net in Base 2 — Upper bound on s

There is no (143, 218, 801)-net in base 2, because

1 times m-reduction [i] would yield (143, 217, 801)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 215463 909990 084691 718766 355516 203932 561919 036954 113759 245526 323104 > 2²¹⁷ [i]
