Best Known (12, 12+12, s)-Nets in Base 4

(12, 12+12, 34)-Net over F₄ — Constructive and digital

Digital (12, 24, 34)-net over F₄, using

trace code for nets [i] based on digital (0, 12, 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]

(12, 12+12, 251)-Net in Base 4 — Upper bound on s

There is no (12, 24, 252)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 288 137413 070578 > 4²⁴ [i]
