Digital (55, 80, 379)-net over F₈, using

(u,Â u+v)-construction [i] based on
1. digital (4, 16, 25)-net over F₈, using
  - net from sequence [i] based on digital (4, 24)-sequence over F₈, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 4 and N(F) ≥ 25, using
      - a function field by SÃ©mirat [i]
2. digital (39, 64, 354)-net over F₈, using
  - trace code for nets [i] based on digital (7, 32, 177)-net over F₆₄, using
    - net from sequence [i] based on digital (7, 176)-sequence over F₆₄, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 7 and N(F) ≥ 177, using
        a function field by GarcÃa and Quoos [i]

(55, 55+25, 576)-Net in Base 8 — Constructive

(55, 80, 576)-net in base 8, using

trace code for nets [i] based on (15, 40, 288)-net in base 64, using
- 2 times m-reduction [i] based on (15, 42, 288)-net in base 64, using
  - base change [i] based on digital (9, 36, 288)-net over F₁₂₈, using
    - net from sequence [i] based on digital (9, 287)-sequence over F₁₂₈, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₂₈ with g(F) = 9 and N(F) ≥ 288, using
        a function field by SÃ©mirat [i]

(55, 55+25, 1446)-Net over F₈ — Digital

Digital (55, 80, 1446)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(55, 55+25, 666194)-Net in Base 8 — Upper bound on s

There is no (55, 80, 666195)-net in base 8, because

1 times m-reduction [i] would yield (55, 79, 666195)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 220857 614998 303847 394961 025400 898406 265137 472413 373928 760252 673753 865332 > 8⁷⁹ [i]
