MinT - Best Known (230−77, 230, s)-Nets in Base 2

Best Known (230−77, 230, s)-Nets in Base 2

(230−77, 230, 112)-Net over F₂ — Constructive and digital

Digital (153, 230, 112)-net over F₂, using

10 times m-reduction [i] based on digital (153, 240, 112)-net over F₂, using
- trace code for nets [i] based on digital (33, 120, 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]

(230−77, 230, 156)-Net over F₂ — Digital

Digital (153, 230, 156)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(230−77, 230, 924)-Net in Base 2 — Upper bound on s

There is no (153, 230, 925)-net in base 2, because

1 times m-reduction [i] would yield (153, 229, 925)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 889 153684 660285 295378 685635 718164 587387 766744 412468 305894 848294 760928 > 2²²⁹ [i]
