(149, 198, 1028)-Net over F₄ — Constructive and digital

Digital (149, 198, 1028)-net over F₄, using

4² times duplication [i] based on digital (147, 196, 1028)-net over F₄, using
- trace code for nets [i] based on digital (0, 49, 257)-net over F₂₅₆, using
  - net from sequence [i] based on digital (0, 256)-sequence over F₂₅₆, using
    - generalized Faure sequence [i]
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅₆ with g(F) = 0 and N(F) ≥ 257, using
      - the rational function field F₂₅₆(x) [i]

(149, 198, 285838)-Net in Base 4 — Upper bound on s

There is no (149, 198, 285839)-net in base 4, because

1 times m-reduction [i] would yield (149, 197, 285839)-net in base 4, but
