Best Known (231−111, 231, s)-Nets in Base 2

(231−111, 231, 57)-Net over F₂ — Constructive and digital

Digital (120, 231, 57)-net over F₂, using

t-expansion [i] based on digital (110, 231, 57)-net over F₂, using
- net from sequence [i] based on digital (110, 56)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 69, N(F)Â =Â 48, 1 place with degree 2, and 8 places with degree 6 [i] based on function field F/F₂ with g(F) = 69 and N(F) ≥ 48, using an explicitly constructive algebraic function field [i]

(231−111, 231, 73)-Net over F₂ — Digital

Digital (120, 231, 73)-net over F₂, using

t-expansion [i] based on digital (114, 231, 73)-net over F₂, using
- net from sequence [i] based on digital (114, 72)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 114 and N(F) ≥ 73, using
    - Drinfeld modules of rank 1 [i]

(231−111, 231, 254)-Net in Base 2 — Upper bound on s

There is no (120, 231, 255)-net in base 2, because

3 times m-reduction [i] would yield (120, 228, 255)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²²⁸, 255, S₂, 108), but
  - the linear programming bound shows that MÂ â‰¥ 2 619796 018994 278921 458293 535821 563915 180233 403060 117761 392727 838179 034558 103552 / 5817 546149 > 2²²⁸ [i]
