MinT - Best Known (205−127, 205, s)-Nets in Base 4

Best Known (205−127, 205, s)-Nets in Base 4

(205−127, 205, 104)-Net over F₄ — Constructive and digital

Digital (78, 205, 104)-net over F₄, using

t-expansion [i] based on digital (73, 205, 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]

(205−127, 205, 112)-Net over F₄ — Digital

Digital (78, 205, 112)-net over F₄, using

t-expansion [i] based on digital (73, 205, 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]

(205−127, 205, 670)-Net in Base 4 — Upper bound on s

There is no (78, 205, 671)-net in base 4, because

1 times m-reduction [i] would yield (78, 204, 671)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 683 715045 535744 506517 413180 929340 625329 718274 862653 243258 758756 283939 628385 299250 764229 339798 818575 094759 094144 958739 374320 > 4²⁰⁴ [i]
