    - net from sequence [i] based on digital (16, 369)-sequence over F₈₁, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 16 and N(F) ≥ 370, using
        a function field by GarcÃa and Quoos [i]

(47, 47+33, 1879)-Net over F₂₇ — Digital

Digital (47, 80, 1879)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(47, 47+33, 3054378)-Net in Base 27 — Upper bound on s

There is no (47, 80, 3054379)-net in base 27, because

1 times m-reduction [i] would yield (47, 79, 3054379)-net in base 27, but
