Best Known (84−62, 84, s)-Nets in Base 4

(84−62, 84, 34)-Net over F₄ — Constructive and digital

Digital (22, 84, 34)-net over F₄, using

t-expansion [i] based on digital (21, 84, 34)-net over F₄, using
- net from sequence [i] based on digital (21, 33)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 21 and N(F) ≥ 34, using
    - T₅ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(84−62, 84, 44)-Net over F₄ — Digital

Digital (22, 84, 44)-net over F₄, using

t-expansion [i] based on digital (21, 84, 44)-net over F₄, using
- net from sequence [i] based on digital (21, 43)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 21 and N(F) ≥ 44, using
    - a curve from the manYPoints database [i]

(84−62, 84, 96)-Net in Base 4 — Upper bound on s

There is no (22, 84, 97)-net in base 4, because

extracting embedded orthogonal array [i] would yield OA(4⁸⁴, 97, S₄, 62), but
- the linear programming bound shows that MÂ â‰¥ 1 171133 092329 712265 557448 798148 266278 121440 437172 708782 899200 / 2957 160437 > 4⁸⁴ [i]
