Best Known (256−122, 256, s)-Nets in Base 2

(256−122, 256, 62)-Net over F₂ — Constructive and digital

Digital (134, 256, 62)-net over F₂, using

(u,Â u+v)-construction [i] based on
1. digital (19, 80, 20)-net over F₂, using
  - net from sequence [i] based on digital (19, 19)-sequence over F₂, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 19 and N(F) ≥ 20, using
      - an explicitly constructive algebraic function field [i]
2. digital (54, 176, 42)-net over F₂, using
  - net from sequence [i] based on digital (54, 41)-sequence over F₂, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 54 and N(F) ≥ 42, using
      - an explicitly constructive algebraic function field [i]

(256−122, 256, 81)-Net over F₂ — Digital

Digital (134, 256, 81)-net over F₂, using

t-expansion [i] based on digital (126, 256, 81)-net over F₂, using
- net from sequence [i] based on digital (126, 80)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 126 and N(F) ≥ 81, using
    - Drinfeld modules of rank 1 [i]

(256−122, 256, 299)-Net in Base 2 — Upper bound on s

There is no (134, 256, 300)-net in base 2, because

12 times m-reduction [i] would yield (134, 244, 300)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²⁴⁴, 300, S₂, 110), but
  - the linear programming bound shows that MÂ â‰¥ 727209 932038 995964 963694 786156 506719 769259 430085 807852 102717 045283 079365 167115 254635 995296 956416 / 21378 491075 472167 578125 > 2²⁴⁴ [i]
