Best Known (62, 62+83, s)-Nets in Base 4

(62, 62+83, 66)-Net over F₄ — Constructive and digital

Digital (62, 145, 66)-net over F₄, using

t-expansion [i] based on digital (49, 145, 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]

(62, 62+83, 99)-Net over F₄ — Digital

Digital (62, 145, 99)-net over F₄, using

t-expansion [i] based on digital (61, 145, 99)-net over F₄, using
- net from sequence [i] based on digital (61, 98)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 61 and N(F) ≥ 99, using
    - Drinfeld modules of rank 1 [i]

(62, 62+83, 667)-Net in Base 4 — Upper bound on s

There is no (62, 145, 668)-net in base 4, because

1 times m-reduction [i] would yield (62, 144, 668)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 517 088265 479588 558159 352051 491520 252719 120065 886509 133776 989573 155794 121163 096182 463820 > 4¹⁴⁴ [i]
