MinT - Best Known (20−10, 20, s)-Nets in Base 4

Best Known (20−10, 20, s)-Nets in Base 4

(20−10, 20, 34)-Net over F₄ — Constructive and digital

Digital (10, 20, 34)-net over F₄, using

trace code for nets [i] based on digital (0, 10, 17)-net over F₁₆, using
- net from sequence [i] based on digital (0, 16)-sequence over F₁₆, using
  - generalized Faure sequence [i]
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 0 and N(F) ≥ 17, using
    - the rational function field F₁₆(x) [i]
  - Niederreiter sequence [i]

(20−10, 20, 218)-Net in Base 4 — Upper bound on s

There is no (10, 20, 219)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1 107806 785588 > 4²⁰ [i]
