  - net from sequence [i] based on digital (3, 27)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 3 and N(F) ≥ 28, using
      - the Hermitian function field over F₉ [i]
2. digital (17, 97, 74)-net over F₉, using

(140−80, 140, 4286)-Net in Base 9 — Upper bound on s

There is no (60, 140, 4287)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 39 529892 569414 720655 274098 470422 307769 500852 731970 470688 286458 376429 608772 970289 770892 485773 641437 583910 986887 918254 590468 740029 599425 > 9¹⁴⁰ [i]
