Best Known (80, 225, s)-Nets in Base 4

(80, 225, 104)-Net over F₄ — Constructive and digital

Digital (80, 225, 104)-net over F₄, using

t-expansion [i] based on digital (73, 225, 104)-net over F₄, using
- net from sequence [i] based on digital (73, 103)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 104, using
    - F₆ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(80, 225, 112)-Net over F₄ — Digital

Digital (80, 225, 112)-net over F₄, using

t-expansion [i] based on digital (73, 225, 112)-net over F₄, using
- net from sequence [i] based on digital (73, 111)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 112, using
    - Drinfeld modules of rank 1 [i]

(80, 225, 630)-Net in Base 4 — Upper bound on s

There is no (80, 225, 631)-net in base 4, because

1 times m-reduction [i] would yield (80, 224, 631)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 795 049020 394701 453127 906499 788830 162038 383042 885341 429418 118389 037958 823662 211295 948768 655529 262850 380985 770349 520231 003013 553306 934954 > 4²²⁴ [i]
