Best Known (60, 60+123, s)-Nets in Base 4

(60, 60+123, 66)-Net over F₄ — Constructive and digital

Digital (60, 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]

(60, 60+123, 91)-Net over F₄ — Digital

Digital (60, 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]

(60, 60+123, 442)-Net in Base 4 — Upper bound on s

There is no (60, 183, 443)-net in base 4, because

1 times m-reduction [i] would yield (60, 182, 443)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 38 007174 015228 413477 454113 599813 075207 723260 134525 496548 843377 532866 688205 784696 270194 880448 689452 501028 651840 > 4¹⁸² [i]
