MinT - Best Known (195−113, 195, s)-Nets in Base 4

Best Known (195−113, 195, s)-Nets in Base 4

(195−113, 195, 104)-Net over F₄ — Constructive and digital

Digital (82, 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]

(195−113, 195, 129)-Net over F₄ — Digital

Digital (82, 195, 129)-net over F₄, using

t-expansion [i] based on digital (81, 195, 129)-net over F₄, using
- net from sequence [i] based on digital (81, 128)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 81 and N(F) ≥ 129, using
    - Drinfeld modules of rank 1 [i]

(195−113, 195, 836)-Net in Base 4 — Upper bound on s

There is no (82, 195, 837)-net in base 4, because

1 times m-reduction [i] would yield (82, 194, 837)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 661 530421 684726 319075 426733 272509 498461 258175 369097 316710 631792 431258 458954 073680 135127 358852 491230 995549 167062 945960 > 4¹⁹⁴ [i]
