Best Known (80−39, 80, s)-Nets in Base 4

(80−39, 80, 56)-Net over F₄ — Constructive and digital

Digital (41, 80, 56)-net over F₄, using

t-expansion [i] based on digital (33, 80, 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]

      - the Suzuki function field over F₈ [i]

(80−39, 80, 75)-Net over F₄ — Digital

Digital (41, 80, 75)-net over F₄, using

t-expansion [i] based on digital (40, 80, 75)-net over F₄, using
- net from sequence [i] based on digital (40, 74)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 40 and N(F) ≥ 75, using

(80−39, 80, 826)-Net in Base 4 — Upper bound on s

There is no (41, 80, 827)-net in base 4, because

1 times m-reduction [i] would yield (41, 79, 827)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 365894 785508 303805 023349 760159 817700 815318 552836 > 4⁷⁹ [i]
