Best Known (189, 260, s)-Nets in Base 4

(189, 260, 531)-Net over F₄ — Constructive and digital

Digital (189, 260, 531)-net over F₄, using

4² times duplication [i] based on digital (187, 258, 531)-net over F₄, using
- t-expansion [i] based on digital (179, 258, 531)-net over F₄, using
  - trace code for nets [i] based on digital (7, 86, 177)-net over F₆₄, using
    - net from sequence [i] based on digital (7, 176)-sequence over F₆₄, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 7 and N(F) ≥ 177, using
        a function field by GarcÃa and Quoos [i]

(189, 260, 1557)-Net over F₄ — Digital

Digital (189, 260, 1557)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(189, 260, 132218)-Net in Base 4 — Upper bound on s

There is no (189, 260, 132219)-net in base 4, because

1 times m-reduction [i] would yield (189, 259, 132219)-net in base 4, but
