Best Known (256−157, 256, s)-Nets in Base 2

(256−157, 256, 54)-Net over F₂ — Constructive and digital

Digital (99, 256, 54)-net over F₂, using

t-expansion [i] based on digital (95, 256, 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]

(256−157, 256, 65)-Net over F₂ — Digital

Digital (99, 256, 65)-net over F₂, using

t-expansion [i] based on digital (95, 256, 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

(256−157, 256, 189)-Net in Base 2 — Upper bound on s

There is no (99, 256, 190)-net in base 2, because

1 times m-reduction [i] would yield (99, 255, 190)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 73547 801781 426622 569111 417874 057050 622768 864382 674527 091923 141190 288117 553408 > 2²⁵⁵ [i]
