Best Known (216−104, 216, s)-Nets in Base 2

(216−104, 216, 57)-Net over F₂ — Constructive and digital

Digital (112, 216, 57)-net over F₂, using

t-expansion [i] based on digital (110, 216, 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]

(216−104, 216, 72)-Net over F₂ — Digital

Digital (112, 216, 72)-net over F₂, using

t-expansion [i] based on digital (110, 216, 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

(216−104, 216, 238)-Net in Base 2 — Upper bound on s

There is no (112, 216, 239)-net in base 2, because

2 times m-reduction [i] would yield (112, 214, 239)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²¹⁴, 239, S₂, 102), but
  - the linear programming bound shows that MÂ â‰¥ 4 499776 858427 444685 568692 820114 098477 214081 226988 556790 531079 172255 645696 / 143 712023 > 2²¹⁴ [i]
