MinT - Best Known (200−123, 200, s)-Nets in Base 4

Best Known (200−123, 200, s)-Nets in Base 4

(200−123, 200, 104)-Net over F₄ — Constructive and digital

Digital (77, 200, 104)-net over F₄, using

t-expansion [i] based on digital (73, 200, 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]

(200−123, 200, 112)-Net over F₄ — Digital

Digital (77, 200, 112)-net over F₄, using

t-expansion [i] based on digital (73, 200, 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]

(200−123, 200, 674)-Net in Base 4 — Upper bound on s

There is no (77, 200, 675)-net in base 4, because

1 times m-reduction [i] would yield (77, 199, 675)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 699102 046330 238517 668064 328540 344065 854909 880385 822702 686598 937232 662624 384479 970515 586732 664921 854744 539551 861636 236480 > 4¹⁹⁹ [i]
