Best Known (54−23, 54, s)-Nets in Base 16

(54−23, 54, 522)-Net over F₁₆ — Constructive and digital

Digital (31, 54, 522)-net over F₁₆, using

trace code for nets [i] based on digital (4, 27, 261)-net over F₂₅₆, using
- net from sequence [i] based on digital (4, 260)-sequence over F₂₅₆, using
  - Niederreiter sequence [i]

(54−23, 54, 644)-Net over F₁₆ — Digital

Digital (31, 54, 644)-net over F₁₆, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(16⁵⁴, 644, F₁₆, 2, 23) (dual of [(644, 2), 1234, 24]-NRT-code), using
- 2 times NRT-code embedding in larger space [i] based on linear OOA(16⁵⁰, 642, F₁₆, 2, 23) (dual of [(642, 2), 1234, 24]-NRT-code), using
  - extracting embedded OOA [i] based on digital (27, 50, 642)-net over F₁₆, using
    - trace code for nets [i] based on digital (2, 25, 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]

(54−23, 54, 207290)-Net in Base 16 — Upper bound on s

There is no (31, 54, 207291)-net in base 16, because

1 times m-reduction [i] would yield (31, 53, 207291)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 6582 110554 536487 246190 956088 250621 467538 538688 577627 922385 346016 > 16⁵³ [i]
