Best Known (205−101, 205, s)-Nets in Base 2

(205−101, 205, 55)-Net over F₂ — Constructive and digital

Digital (104, 205, 55)-net over F₂, using

t-expansion [i] based on digital (100, 205, 55)-net over F₂, using
- net from sequence [i] based on digital (100, 54)-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 6 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]

(205−101, 205, 65)-Net over F₂ — Digital

Digital (104, 205, 65)-net over F₂, using

t-expansion [i] based on digital (95, 205, 65)-net over F₂, using
- net from sequence [i] based on digital (95, 64)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 95 and N(F) ≥ 65, using

(205−101, 205, 221)-Net in Base 2 — Upper bound on s

There is no (104, 205, 222)-net in base 2, because

1 times m-reduction [i] would yield (104, 204, 222)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2²⁰⁴, 222, S₂, 100), but
  - the linear programming bound shows that MÂ â‰¥ 226 079162 139475 140543 755525 929919 500580 588046 051128 804585 192091 025408 / 6 427377 > 2²⁰⁴ [i]
