    - generalized Faure sequence [i]
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 0 and N(F) ≥ 5, using
      - the rational function field F₄(x) [i]
    - Niederreiter sequence [i]
2. digital (64, 116, 130)-net over F₄, using

Digital (90, 142, 294)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(90, 90+52, 6807)-Net in Base 4 — Upper bound on s

There is no (90, 142, 6808)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 31 120917 364310 023825 580669 803553 040265 993921 622931 113780 155995 125931 570193 154381 911600 > 4¹⁴² [i]
