Best Known (27, 27+21, s)-Nets in Base 16

(27, 27+21, 520)-Net over F₁₆ — Constructive and digital

Digital (27, 48, 520)-net over F₁₆, using

trace code for nets [i] based on digital (3, 24, 260)-net over F₂₅₆, using
- net from sequence [i] based on digital (3, 259)-sequence over F₂₅₆, using
  - Niederreiter sequence [i]

(27, 27+21, 642)-Net over F₁₆ — Digital

Digital (27, 48, 642)-net over F₁₆, using

2 times m-reduction [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]

(27, 27+21, 137794)-Net in Base 16 — Upper bound on s

There is no (27, 48, 137795)-net in base 16, because

1 times m-reduction [i] would yield (27, 47, 137795)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 392 325904 278351 599352 801160 025196 954218 423251 062293 892376 > 16⁴⁷ [i]
