MinT - Best Known (31, 31+23, s)-Nets in Base 4

Best Known (31, 31+23, s)-Nets in Base 4

(31, 31+23, 90)-Net over F₄ — Constructive and digital

Digital (31, 54, 90)-net over F₄, using

trace code for nets [i] based on digital (4, 27, 45)-net over F₁₆, using
- net from sequence [i] based on digital (4, 44)-sequence over F₁₆, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
    - a function field by GarcÃa and Quoos [i]

(31, 31+23, 1293)-Net in Base 4 — Upper bound on s

There is no (31, 54, 1294)-net in base 4, because

1 times m-reduction [i] would yield (31, 53, 1294)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 81 332056 898517 305661 503370 701650 > 4⁵³ [i]
