        net from sequence [i] based on digital (0, 81)-sequence over F₈₁, using
        generalized Faure sequence [i]
        Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 0 and N(F) ≥ 82, using
        the rational function field F₈₁(x) [i]
        Niederreiter sequence [i]
      2. digital (0, 5, 82)-net over F₈₁, using
        net from sequence [i] based on digital (0, 81)-sequence over F₈₁ (see above)
      3. digital (0, 11, 82)-net over F₈₁, using

(38, 59, 44294)-Net over F₈₁ — Digital

Digital (38, 59, 44294)-net over F₈₁, using

Gilbertâ€“VarÅ¡amov bound [i]

(38, 59, large)-Net in Base 81 — Upper bound on s

There is no (38, 59, large)-net in base 81, because

19 times m-reduction [i] would yield (38, 40, large)-net in base 81, but
- mutually orthogonal hypercube bound [i]
