MinT - Best Known (50−47, 50, s)-Nets in Base 256

Best Known (50−47, 50, s)-Nets in Base 256

(50−47, 50, 260)-Net over F₂₅₆ — Constructive and digital

Digital (3, 50, 260)-net over F₂₅₆, using

net from sequence [i] based on digital (3, 259)-sequence over F₂₅₆, using
- Niederreiter sequence [i]

(50−47, 50, 321)-Net over F₂₅₆ — Digital

Digital (3, 50, 321)-net over F₂₅₆, using

t-expansion [i] based on digital (2, 50, 321)-net over F₂₅₆, using
- net from sequence [i] based on digital (2, 320)-sequence over F₂₅₆, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅₆ with g(F) = 2 and N(F) ≥ 321, using
    - sharp bound on the number of rational points on curves with genus 2 [i]

(50−47, 50, 4881)-Net in Base 256 — Upper bound on s

There is no (3, 50, 4882)-net in base 256, because

9 times m-reduction [i] would yield (3, 41, 4882)-net in base 256, but
- the generalized Rao bound for nets shows that 256^mÂ â‰¥ 546 820388 520344 519866 736051 211508 905608 391554 726876 534867 885936 434168 776106 017001 119928 811893 695616 > 256⁴¹ [i]
