MinT - Best Known (185−127, 185, s)-Nets in Base 4

Best Known (185−127, 185, s)-Nets in Base 4

(185−127, 185, 66)-Net over F₄ — Constructive and digital

Digital (58, 185, 66)-net over F₄, using

t-expansion [i] based on digital (49, 185, 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]

(185−127, 185, 91)-Net over F₄ — Digital

Digital (58, 185, 91)-net over F₄, using

t-expansion [i] based on digital (50, 185, 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]

(185−127, 185, 414)-Net in Base 4 — Upper bound on s

There is no (58, 185, 415)-net in base 4, because

1 times m-reduction [i] would yield (58, 184, 415)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 638 371532 818962 575462 149724 332502 866953 664378 737081 511305 996263 954044 936076 314597 954306 561781 316142 218978 927760 > 4¹⁸⁴ [i]
