Best Known (207, 251, s)-Nets in Base 4

(207, 251, 1569)-Net over F₄ — Constructive and digital

Digital (207, 251, 1569)-net over F₄, using

(u,Â u+v)-construction [i] based on
1. digital (13, 35, 30)-net over F₄, using
  - net from sequence [i] based on digital (13, 29)-sequence over F₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 13 and N(F) ≥ 30, using
      - F₄ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]
2. digital (172, 216, 1539)-net over F₄, using
  - trace code for nets [i] based on digital (28, 72, 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]

(207, 251, 18416)-Net over F₄ — Digital

Digital (207, 251, 18416)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(207, 251, large)-Net in Base 4 — Upper bound on s

There is no (207, 251, large)-net in base 4, because

42 times m-reduction [i] would yield (207, 209, large)-net in base 4, but
- mutually orthogonal hypercube bound [i]
