MinT - Best Known (255−147, 255, s)-Nets in Base 2

Best Known (255−147, 255, s)-Nets in Base 2

(255−147, 255, 56)-Net over F₂ — Constructive and digital

Digital (108, 255, 56)-net over F₂, using

t-expansion [i] based on digital (105, 255, 56)-net over F₂, using
- net from sequence [i] based on digital (105, 55)-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 7 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]

(255−147, 255, 65)-Net over F₂ — Digital

Digital (108, 255, 65)-net over F₂, using

t-expansion [i] based on digital (95, 255, 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

(255−147, 255, 218)-Net in Base 2 — Upper bound on s

There is no (108, 255, 219)-net in base 2, because

1 times m-reduction [i] would yield (108, 254, 219)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 36292 904175 160627 204453 086541 493062 990696 916433 275929 888093 587482 531815 019764 > 2²⁵⁴ [i]
