MinT - Best Known (102−57, 102, s)-Nets in Base 4

Best Known (102−57, 102, s)-Nets in Base 4

(102−57, 102, 56)-Net over F₄ — Constructive and digital

Digital (45, 102, 56)-net over F₄, using

t-expansion [i] based on digital (33, 102, 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]

(102−57, 102, 80)-Net over F₄ — Digital

Digital (45, 102, 80)-net over F₄, using

net from sequence [i] based on digital (45, 79)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 45 and N(F) ≥ 80, using
  - Drinfeld modules of rank 1 [i]

(102−57, 102, 536)-Net in Base 4 — Upper bound on s

There is no (45, 102, 537)-net in base 4, because

1 times m-reduction [i] would yield (45, 101, 537)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 6 505343 687427 652341 784599 948187 756927 427814 099195 255481 035136 > 4¹⁰¹ [i]
