Best Known (56, 56+127, s)-Nets in Base 4

(56, 56+127, 66)-Net over F₄ — Constructive and digital

Digital (56, 183, 66)-net over F₄, using

t-expansion [i] based on digital (49, 183, 66)-net over F₄, using
- net from sequence [i] based on digital (49, 65)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 49 and N(F) ≥ 66, using
    - T₆ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(56, 56+127, 91)-Net over F₄ — Digital

Digital (56, 183, 91)-net over F₄, using

t-expansion [i] based on digital (50, 183, 91)-net over F₄, using
- net from sequence [i] based on digital (50, 90)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 50 and N(F) ≥ 91, using
    - a curve from the manYPoints database [i]

(56, 56+127, 394)-Net in Base 4 — Upper bound on s

There is no (56, 183, 395)-net in base 4, because

1 times m-reduction [i] would yield (56, 182, 395)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 39 486108 762559 513112 446308 397853 234647 543332 489395 932489 659137 570984 622422 878347 827935 114425 607394 952117 756160 > 4¹⁸² [i]
