MinT - Best Known (20, 20+16, s)-Nets in Base 4

Best Known (20, 20+16, s)-Nets in Base 4

(20, 20+16, 66)-Net over F₄ — Constructive and digital

Digital (20, 36, 66)-net over F₄, using

trace code for nets [i] based on digital (2, 18, 33)-net over F₁₆, using
- net from sequence [i] based on digital (2, 32)-sequence over F₁₆, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 2 and N(F) ≥ 33, using
    - a function field by SÃ©mirat [i]

(20, 20+16, 636)-Net in Base 4 — Upper bound on s

There is no (20, 36, 637)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 4763 341323 808008 392725 > 4³⁶ [i]
