MinT - Best Known (233−131, 233, s)-Nets in Base 4

Best Known (233−131, 233, s)-Nets in Base 4

(233−131, 233, 104)-Net over F₄ — Constructive and digital

Digital (102, 233, 104)-net over F₄, using

t-expansion [i] based on digital (73, 233, 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]

(233−131, 233, 144)-Net over F₄ — Digital

Digital (102, 233, 144)-net over F₄, using

t-expansion [i] based on digital (91, 233, 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]

(233−131, 233, 1123)-Net in Base 4 — Upper bound on s

There is no (102, 233, 1124)-net in base 4, because

1 times m-reduction [i] would yield (102, 232, 1124)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 49 104159 197870 060837 468591 203528 288504 544593 199021 392697 878289 583558 076584 782222 812336 099469 464219 251239 219692 498655 031002 642361 355871 367091 > 4²³² [i]
