Best Known (244−131, 244, s)-Nets in Base 2

(244−131, 244, 57)-Net over F₂ — Constructive and digital

Digital (113, 244, 57)-net over F₂, using

t-expansion [i] based on digital (110, 244, 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]

(244−131, 244, 72)-Net over F₂ — Digital

Digital (113, 244, 72)-net over F₂, using

t-expansion [i] based on digital (110, 244, 72)-net over F₂, using
- net from sequence [i] based on digital (110, 71)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 110 and N(F) ≥ 72, using
    - Drinfeld modules of rank 1 [i]

(244−131, 244, 238)-Net in Base 2 — Upper bound on s

There is no (113, 244, 239)-net in base 2, because

25 times m-reduction [i] would yield (113, 219, 239)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²¹⁹, 239, S₂, 106), but
  - the linear programming bound shows that MÂ â‰¥ 241561 122137 669732 560216 455179 695890 835788 814025 963529 430688 347832 975360 / 208437 > 2²¹⁹ [i]
