Best Known (189−98, 189, s)-Nets in Base 4

(189−98, 189, 104)-Net over F₄ — Constructive and digital

Digital (91, 189, 104)-net over F₄, using

t-expansion [i] based on digital (73, 189, 104)-net over F₄, using
- net from sequence [i] based on digital (73, 103)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 104, using
    - F₆ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(189−98, 189, 144)-Net over F₄ — Digital

Digital (91, 189, 144)-net over F₄, using

net from sequence [i] based on digital (91, 143)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 91 and N(F) ≥ 144, using
  - Drinfeld modules of rank 1 [i]

(189−98, 189, 1298)-Net in Base 4 — Upper bound on s

There is no (91, 189, 1299)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 638423 394380 045019 610317 819040 834903 704586 216227 554293 539444 006223 922127 279386 505857 054119 147342 300978 226050 943248 > 4¹⁸⁹ [i]
