MinT - Best Known (120−83, 120, s)-Nets in Base 4

Best Known (120−83, 120, s)-Nets in Base 4

(120−83, 120, 56)-Net over F₄ — Constructive and digital

Digital (37, 120, 56)-net over F₄, using

t-expansion [i] based on digital (33, 120, 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]

(120−83, 120, 66)-Net over F₄ — Digital

Digital (37, 120, 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]

(120−83, 120, 268)-Net in Base 4 — Upper bound on s

There is no (37, 120, 269)-net in base 4, because

1 times m-reduction [i] would yield (37, 119, 269)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 475023 807511 312234 344987 641095 859228 426600 822466 701133 163060 298077 220224 > 4¹¹⁹ [i]
