Best Known (246−49, 246, s)-Nets in Base 2

(246−49, 246, 266)-Net over F₂ — Constructive and digital

Digital (197, 246, 266)-net over F₂, using

(u,Â u+v)-construction [i] based on
1. digital (2, 26, 6)-net over F₂, using
  - net from sequence [i] based on digital (2, 5)-sequence over F₂, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 2 and N(F) ≥ 6, using
      - an explicitly constructive algebraic function field [i]
  - Niederreiterâ€“Xing sequence (PirÅ¡iÄ‡ implementation) with equidistant coordinate [i]
2. digital (171, 220, 260)-net over F₂, using
  - trace code for nets [i] based on digital (6, 55, 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]

(246−49, 246, 624)-Net over F₂ — Digital

Digital (197, 246, 624)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(246−49, 246, 11562)-Net in Base 2 — Upper bound on s

There is no (197, 246, 11563)-net in base 2, because

1 times m-reduction [i] would yield (197, 245, 11563)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 56 610061 771815 303959 594499 227262 098736 502692 855957 806427 513300 163772 570986 > 2²⁴⁵ [i]
