MinT - Best Known (247−67, 247, s)-Nets in Base 2

Best Known (247−67, 247, s)-Nets in Base 2

(247−67, 247, 195)-Net over F₂ — Constructive and digital

Digital (180, 247, 195)-net over F₂, using

2 times m-reduction [i] based on digital (180, 249, 195)-net over F₂, using
- trace code for nets [i] based on digital (14, 83, 65)-net over F₈, using
  - net from sequence [i] based on digital (14, 64)-sequence over F₈, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 14 and N(F) ≥ 65, using
      - the Suzuki function field over F₈ [i]

(247−67, 247, 272)-Net over F₂ — Digital

Digital (180, 247, 272)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(247−67, 247, 2260)-Net in Base 2 — Upper bound on s

There is no (180, 247, 2261)-net in base 2, because

1 times m-reduction [i] would yield (180, 246, 2261)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 114 179479 769953 273520 442723 121136 151641 059585 401604 658598 345829 481162 918884 > 2²⁴⁶ [i]
