MinT - Best Known (189−61, 189, s)-Nets in Base 2

Best Known (189−61, 189, s)-Nets in Base 2

(189−61, 189, 112)-Net over F₂ — Constructive and digital

Digital (128, 189, 112)-net over F₂, using

1 times m-reduction [i] based on digital (128, 190, 112)-net over F₂, using
- trace code for nets [i] based on digital (33, 95, 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]

(189−61, 189, 143)-Net over F₂ — Digital

Digital (128, 189, 143)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(189−61, 189, 883)-Net in Base 2 — Upper bound on s

There is no (128, 189, 884)-net in base 2, because

1 times m-reduction [i] would yield (128, 188, 884)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 394 858279 639681 210952 180958 425012 606327 047725 982645 074296 > 2¹⁸⁸ [i]
