  - net from sequence [i] based on digital (6, 33)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 6 and N(F) ≥ 34, using
      - a function field by SÃ©mirat [i]

(31, 31+18, 81)-Net over F₃ — Digital

Digital (31, 49, 81)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(31, 31+18, 812)-Net in Base 3 — Upper bound on s

There is no (31, 49, 813)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 240325 704168 961731 556923 > 3⁴⁹ [i]
