  - net from sequence [i] based on digital (4, 14)-sequence over F₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 4 and N(F) ≥ 15, using
      - an explicitly constructive algebraic function field [i]
2. digital (7, 37, 21)-net over F₄, using

(26, 56, 366)-Net in Base 4 — Upper bound on s

There is no (26, 56, 367)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 5216 815287 489952 795376 217779 484652 > 4⁵⁶ [i]
