MinT - Best Known (195−117, 195, s)-Nets in Base 4

Best Known (195−117, 195, s)-Nets in Base 4

(195−117, 195, 104)-Net over F₄ — Constructive and digital

Digital (78, 195, 104)-net over F₄, using

t-expansion [i] based on digital (73, 195, 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]

(195−117, 195, 112)-Net over F₄ — Digital

Digital (78, 195, 112)-net over F₄, using

t-expansion [i] based on digital (73, 195, 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]

(195−117, 195, 725)-Net in Base 4 — Upper bound on s

There is no (78, 195, 726)-net in base 4, because

1 times m-reduction [i] would yield (78, 194, 726)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 642 263780 014457 885681 765867 975765 573831 746862 092613 624903 463659 258510 888196 750937 972793 407151 095887 754883 774426 252656 > 4¹⁹⁴ [i]
