      - 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]

(60, 60+49, 1307)-Net over F₂₇ — Digital

Digital (60, 109, 1307)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(60, 60+49, 1041168)-Net in Base 27 — Upper bound on s

There is no (60, 109, 1041169)-net in base 27, because

1 times m-reduction [i] would yield (60, 108, 1041169)-net in base 27, but
