MinT - Best Known (214−137, 214, s)-Nets in Base 4

Best Known (214−137, 214, s)-Nets in Base 4

(214−137, 214, 104)-Net over F₄ — Constructive and digital

Digital (77, 214, 104)-net over F₄, using

t-expansion [i] based on digital (73, 214, 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]

(214−137, 214, 112)-Net over F₄ — Digital

Digital (77, 214, 112)-net over F₄, using

t-expansion [i] based on digital (73, 214, 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]

(214−137, 214, 615)-Net in Base 4 — Upper bound on s

There is no (77, 214, 616)-net in base 4, because

1 times m-reduction [i] would yield (77, 213, 616)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 174 788830 422383 790201 769946 203738 488781 659853 655053 122431 786245 891242 329311 536421 091431 591057 483617 320242 899718 925969 516696 626333 > 4²¹³ [i]
