(125, 200, 139)-Net over F₄ — Constructive and digital

Digital (125, 200, 139)-net over F₄, using

(u,Â u+v)-construction [i] based on
1. digital (1, 38, 9)-net over F₄, using
  - net from sequence [i] based on digital (1, 8)-sequence over F₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 1 and N(F) ≥ 9, using
      - the Hermitian function field over F₄ [i]
2. digital (87, 162, 130)-net over F₄, using

(125, 200, 364)-Net over F₄ — Digital

Digital (125, 200, 364)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(125, 200, 8420)-Net in Base 4 — Upper bound on s

There is no (125, 200, 8421)-net in base 4, because

1 times m-reduction [i] would yield (125, 199, 8421)-net in base 4, but
