MinT - Best Known (150−77, 150, s)-Nets in Base 4

Best Known (150−77, 150, s)-Nets in Base 4

(150−77, 150, 104)-Net over F₄ — Constructive and digital

Digital (73, 150, 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]

(150−77, 150, 112)-Net over F₄ — Digital

Digital (73, 150, 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]

(150−77, 150, 1118)-Net in Base 4 — Upper bound on s

There is no (73, 150, 1119)-net in base 4, because

1 times m-reduction [i] would yield (73, 149, 1119)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 520490 805528 707272 469877 856657 361070 667529 557016 125844 548363 923085 336127 902023 110177 229670 > 4¹⁴⁹ [i]
