Best Known (60, 161, s)-Nets in Base 4

(60, 161, 66)-Net over F₄ — Constructive and digital

Digital (60, 161, 66)-net over F₄, using

t-expansion [i] based on digital (49, 161, 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]

(60, 161, 91)-Net over F₄ — Digital

Digital (60, 161, 91)-net over F₄, using

t-expansion [i] based on digital (50, 161, 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]

(60, 161, 508)-Net in Base 4 — Upper bound on s

There is no (60, 161, 509)-net in base 4, because

1 times m-reduction [i] would yield (60, 160, 509)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 253226 376163 834498 428248 847725 677997 206495 250525 877667 576223 441253 753763 313313 999829 730287 764386 > 4¹⁶⁰ [i]
