MinT - Best Known (260−103, 260, s)-Nets in Base 4

Best Known (260−103, 260, s)-Nets in Base 4

(260−103, 260, 160)-Net over F₄ — Constructive and digital

Digital (157, 260, 160)-net over F₄, using

(u,Â u+v)-construction [i] based on
1. digital (33, 84, 56)-net over F₄, using
  - net from sequence [i] based on digital (33, 55)-sequence over F₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 33 and N(F) ≥ 56, using
      - F₅ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]
2. digital (73, 176, 104)-net over F₄, using
  - net from sequence [i] based on digital (73, 103)-sequence over F₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 104, using
      - F₆ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(260−103, 260, 381)-Net over F₄ — Digital

Digital (157, 260, 381)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(260−103, 260, 7513)-Net in Base 4 — Upper bound on s

There is no (157, 260, 7514)-net in base 4, because

1 times m-reduction [i] would yield (157, 259, 7514)-net in base 4, but
