Best Known (62, 62+97, s)-Nets in Base 4

(62, 62+97, 66)-Net over F₄ — Constructive and digital

Digital (62, 159, 66)-net over F₄, using

t-expansion [i] based on digital (49, 159, 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+97, 99)-Net over F₄ — Digital

Digital (62, 159, 99)-net over F₄, using

t-expansion [i] based on digital (61, 159, 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+97, 560)-Net in Base 4 — Upper bound on s

There is no (62, 159, 561)-net in base 4, because

1 times m-reduction [i] would yield (62, 158, 561)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 139023 791821 416392 075659 971538 987032 610490 167876 977340 621945 524211 556609 495359 374073 070597 702545 > 4¹⁵⁸ [i]
