(155, 206, 1028)-Net over F₄ — Constructive and digital

Digital (155, 206, 1028)-net over F₄, using

4² times duplication [i] based on digital (153, 204, 1028)-net over F₄, using
- trace code for nets [i] based on digital (0, 51, 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]

Digital (155, 206, 1988)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(155, 206, 293336)-Net in Base 4 — Upper bound on s

There is no (155, 206, 293337)-net in base 4, because

1 times m-reduction [i] would yield (155, 205, 293337)-net in base 4, but
