Best Known (195−97, 195, s)-Nets in Base 2

(195−97, 195, 54)-Net over F₂ — Constructive and digital

Digital (98, 195, 54)-net over F₂, using

t-expansion [i] based on digital (95, 195, 54)-net over F₂, using
- net from sequence [i] based on digital (95, 53)-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 5 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]

(195−97, 195, 65)-Net over F₂ — Digital

Digital (98, 195, 65)-net over F₂, using

t-expansion [i] based on digital (95, 195, 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

(195−97, 195, 210)-Net over F₂ — Upper bound on s (digital)

There is no digital (98, 195, 211)-net over F₂, because

1 times m-reduction [i] would yield digital (98, 194, 211)-net over F₂, but
- extracting embedded orthogonal array [i] would yield linear OA(2¹⁹⁴, 211, F₂, 96) (dual of [211, 17, 97]-code), but
  - residual code [i] would yield OA(2⁹⁸, 114, S₂, 48), but
    - the linear programming bound shows that MÂ â‰¥ 141449 524575 866749 536608 130468 675584 / 431375 > 2⁹⁸ [i]

(195−97, 195, 243)-Net in Base 2 — Upper bound on s

There is no (98, 195, 244)-net in base 2, because

1 times m-reduction [i] would yield (98, 194, 244)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 25613 547661 260286 650648 885914 815301 863119 291542 693576 410711 > 2¹⁹⁴ [i]
