MinT - Best Known (124−85, 124, s)-Nets in Base 4

Best Known (124−85, 124, s)-Nets in Base 4

(124−85, 124, 56)-Net over F₄ — Constructive and digital

Digital (39, 124, 56)-net over F₄, using

t-expansion [i] based on digital (33, 124, 56)-net over F₄, using
- net from sequence [i] based on digital (33, 55)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 33 and N(F) ≥ 56, using
    - F₅ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(124−85, 124, 66)-Net over F₄ — Digital

Digital (39, 124, 66)-net over F₄, using

t-expansion [i] based on digital (37, 124, 66)-net over F₄, using
- net from sequence [i] based on digital (37, 65)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 37 and N(F) ≥ 66, using
    - Drinfeld modules of rank 1 [i]

(124−85, 124, 285)-Net in Base 4 — Upper bound on s

There is no (39, 124, 286)-net in base 4, because

1 times m-reduction [i] would yield (39, 123, 286)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 114 552367 255478 762577 585643 894307 018724 720222 010332 791070 199593 224857 999120 > 4¹²³ [i]
