      - net from sequence [i] based on digital (0, 25)-sequence over F₂₅, using
        generalized Faure sequence [i]
        Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅ with g(F) = 0 and N(F) ≥ 26, using
        the rational function field F₂₅(x) [i]
        Niederreiter sequence [i]
    3. digital (0, 7, 26)-net over F₂₅, using

(38, 38+14, 92254)-Net over F₂₅ — Digital

Digital (38, 52, 92254)-net over F₂₅, using

Gilbertâ€“VarÅ¡amov bound [i]

(38, 38+14, large)-Net in Base 25 — Upper bound on s

There is no (38, 52, large)-net in base 25, because

12 times m-reduction [i] would yield (38, 40, large)-net in base 25, but
- mutually orthogonal hypercube bound [i]
