Best Known (193, 193+47, s)-Nets in Base 2

(193, 193+47, 269)-Net over F₂ — Constructive and digital

Digital (193, 240, 269)-net over F₂, using

(u,Â u+v)-construction [i] based on
1. digital (5, 28, 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 (165, 212, 260)-net over F₂, using
  - trace code for nets [i] based on digital (6, 53, 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]

(193, 193+47, 644)-Net over F₂ — Digital

Digital (193, 240, 644)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(193, 193+47, 12629)-Net in Base 2 — Upper bound on s

There is no (193, 240, 12630)-net in base 2, because

1 times m-reduction [i] would yield (193, 239, 12630)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 884307 850829 703235 518814 448158 958144 762576 513604 447652 693202 793008 418236 > 2²³⁹ [i]
