MinT - Best Known (154−79, 154, s)-Nets in Base 4

Best Known (154−79, 154, s)-Nets in Base 4

(154−79, 154, 104)-Net over F₄ — Constructive and digital

Digital (75, 154, 104)-net over F₄, using

t-expansion [i] based on digital (73, 154, 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]

(154−79, 154, 112)-Net over F₄ — Digital

Digital (75, 154, 112)-net over F₄, using

t-expansion [i] based on digital (73, 154, 112)-net over F₄, using
- net from sequence [i] based on digital (73, 111)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 112, using
    - Drinfeld modules of rank 1 [i]

(154−79, 154, 1149)-Net in Base 4 — Upper bound on s

There is no (75, 154, 1150)-net in base 4, because

1 times m-reduction [i] would yield (75, 153, 1150)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 133 515247 305517 615167 318181 739903 562906 461290 823511 219537 492779 041886 863867 918950 146461 387444 > 4¹⁵³ [i]
