MinT - Best Known (109, 109+123, s)-Nets in Base 4

Best Known (109, 109+123, s)-Nets in Base 4

(109, 109+123, 130)-Net over F₄ — Constructive and digital

Digital (109, 232, 130)-net over F₄, using

t-expansion [i] based on digital (105, 232, 130)-net over F₄, using
- net from sequence [i] based on digital (105, 129)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 105 and N(F) ≥ 130, using
    - T₇ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(109, 109+123, 165)-Net over F₄ — Digital

Digital (109, 232, 165)-net over F₄, using

net from sequence [i] based on digital (109, 164)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 109 and N(F) ≥ 165, using
  - Drinfeld modules of rank 1 [i]

(109, 109+123, 1446)-Net in Base 4 — Upper bound on s

There is no (109, 232, 1447)-net in base 4, because

1 times m-reduction [i] would yield (109, 231, 1447)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 080214 198020 469117 151149 468837 124217 400043 741526 817087 363911 831795 662422 883559 531954 144957 422056 016236 746476 341004 290022 003830 929365 272736 > 4²³¹ [i]
