MinT - Best Known (107−67, 107, s)-Nets in Base 4

Best Known (107−67, 107, s)-Nets in Base 4

(107−67, 107, 56)-Net over F₄ — Constructive and digital

Digital (40, 107, 56)-net over F₄, using

t-expansion [i] based on digital (33, 107, 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]

(107−67, 107, 75)-Net over F₄ — Digital

Digital (40, 107, 75)-net over F₄, using

net from sequence [i] based on digital (40, 74)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 40 and N(F) ≥ 75, using
  - Drinfeld modules of rank 1 [i]

(107−67, 107, 350)-Net in Base 4 — Upper bound on s

There is no (40, 107, 351)-net in base 4, because

1 times m-reduction [i] would yield (40, 106, 351)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 6861 046871 448025 637320 217965 253545 547948 588323 604140 037871 482716 > 4¹⁰⁶ [i]
