Best Known (39, 39+39, s)-Nets in Base 25

(39, 39+39, 252)-Net over F₂₅ — Constructive and digital

Digital (39, 78, 252)-net over F₂₅, using

(u,Â u+v)-construction [i] based on
1. digital (10, 29, 126)-net over F₂₅, using
  - net from sequence [i] based on digital (10, 125)-sequence over F₂₅, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅ with g(F) = 10 and N(F) ≥ 126, using
      - the Hermitian function field over F₂₅ [i]
2. digital (10, 49, 126)-net over F₂₅, using
  - net from sequence [i] based on digital (10, 125)-sequence over F₂₅ (see above)

(39, 39+39, 479)-Net over F₂₅ — Digital

Digital (39, 78, 479)-net over F₂₅, using

Gilbertâ€“VarÅ¡amov bound [i]

(39, 39+39, 152866)-Net in Base 25 — Upper bound on s

There is no (39, 78, 152867)-net in base 25, because

1 times m-reduction [i] would yield (39, 77, 152867)-net in base 25, but
