MinT - Best Known (39−13, 39, s)-Nets in Base 4

Best Known (39−13, 39, s)-Nets in Base 4

(39−13, 39, 195)-Net over F₄ — Constructive and digital

Digital (26, 39, 195)-net over F₄, using

trace code for nets [i] based on digital (0, 13, 65)-net over F₆₄, using
- net from sequence [i] based on digital (0, 64)-sequence over F₆₄, using
  - generalized Faure sequence [i]
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 0 and N(F) ≥ 65, using
    - the rational function field F₆₄(x) [i]
  - Niederreiter sequence [i]

(39−13, 39, 6484)-Net in Base 4 — Upper bound on s

There is no (26, 39, 6485)-net in base 4, because

1 times m-reduction [i] would yield (26, 38, 6485)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 75624 401376 136603 359352 > 4³⁸ [i]
