MinT - Best Known (194−121, 194, s)-Nets in Base 4

Best Known (194−121, 194, s)-Nets in Base 4

(194−121, 194, 104)-Net over F₄ — Constructive and digital

Digital (73, 194, 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]

(194−121, 194, 112)-Net over F₄ — Digital

Digital (73, 194, 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]

(194−121, 194, 619)-Net in Base 4 — Upper bound on s

There is no (73, 194, 620)-net in base 4, because

1 times m-reduction [i] would yield (73, 193, 620)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 158 338387 706283 839879 140262 270618 951625 376912 962772 665983 745066 764850 497072 125868 580446 817279 091351 289613 971227 263760 > 4¹⁹³ [i]
