Best Known (249−49, 249, s)-Nets in Base 2

(249−49, 249, 269)-Net over F₂ — Constructive and digital

Digital (200, 249, 269)-net over F₂, using

(u,Â u+v)-construction [i] based on
1. digital (5, 29, 9)-net over F₂, using
  - net from sequence [i] based on digital (5, 8)-sequence over F₂, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 5 and N(F) ≥ 9, 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]

(249−49, 249, 654)-Net over F₂ — Digital

Digital (200, 249, 654)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(249−49, 249, 12612)-Net in Base 2 — Upper bound on s

There is no (200, 249, 12613)-net in base 2, because

1 times m-reduction [i] would yield (200, 248, 12613)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 453 099382 385327 200546 808965 772029 391477 565769 176048 143263 488843 004704 316376 > 2²⁴⁸ [i]
