Best Known (189, 189+39, s)-Nets in Base 4

(189, 189+39, 1560)-Net over F₄ — Constructive and digital

Digital (189, 228, 1560)-net over F₄, using

4¹ times duplication [i] based on digital (188, 227, 1560)-net over F₄, using
- (u,Â u+v)-construction [i] based on
  1. digital (7, 26, 21)-net over F₄, using
    - net from sequence [i] based on digital (7, 20)-sequence over F₄, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 7 and N(F) ≥ 21, using
        an explicitly constructive algebraic function field [i]
  2. digital (162, 201, 1539)-net over F₄, using
    - trace code for nets [i] based on digital (28, 67, 513)-net over F₆₄, using
      - net from sequence [i] based on digital (28, 512)-sequence over F₆₄, using
        Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 28 and N(F) ≥ 513, using
        the Hermitian function field over F₆₄ [i]

(189, 189+39, 20532)-Net over F₄ — Digital

Digital (189, 228, 20532)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(189, 189+39, large)-Net in Base 4 — Upper bound on s

There is no (189, 228, large)-net in base 4, because

37 times m-reduction [i] would yield (189, 191, large)-net in base 4, but
- mutually orthogonal hypercube bound [i]
