Best Known (78, 78+157, s)-Nets in Base 4

(78, 78+157, 104)-Net over F₄ — Constructive and digital

Digital (78, 235, 104)-net over F₄, using

t-expansion [i] based on digital (73, 235, 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]

(78, 78+157, 112)-Net over F₄ — Digital

Digital (78, 235, 112)-net over F₄, using

t-expansion [i] based on digital (73, 235, 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]

(78, 78+157, 574)-Net in Base 4 — Upper bound on s

There is no (78, 235, 575)-net in base 4, because

1 times m-reduction [i] would yield (78, 234, 575)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 778 836909 735369 939966 791943 433012 478667 583134 750327 834626 899982 043249 451077 879991 896457 214714 236743 130929 316258 989738 709134 794165 213594 206840 > 4²³⁴ [i]
