Best Known (77, 77+147, s)-Nets in Base 4

(77, 77+147, 104)-Net over F₄ — Constructive and digital

Digital (77, 224, 104)-net over F₄, using

t-expansion [i] based on digital (73, 224, 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]

(77, 77+147, 112)-Net over F₄ — Digital

Digital (77, 224, 112)-net over F₄, using

t-expansion [i] based on digital (73, 224, 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]

(77, 77+147, 586)-Net in Base 4 — Upper bound on s

There is no (77, 224, 587)-net in base 4, because

1 times m-reduction [i] would yield (77, 223, 587)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 195 520044 200692 557262 189503 097634 115777 985904 534433 692052 312274 576751 927851 200417 902202 332555 369416 440733 214789 870792 701094 197660 045090 > 4²²³ [i]
