  - a curve from the manYPoints database [i]

(18, 18+45, 177)-Net in Base 32 — Constructive

(18, 63, 177)-net in base 32, using

3 times m-reduction [i] based on (18, 66, 177)-net in base 32, using
- base change [i] based on digital (7, 55, 177)-net over F₆₄, using
  - net from sequence [i] based on digital (7, 176)-sequence over F₆₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 7 and N(F) ≥ 177, using
      - a function field by GarcÃa and Quoos [i]

(18, 18+45, 5085)-Net in Base 32 — Upper bound on s

There is no (18, 63, 5086)-net in base 32, because

1 times m-reduction [i] would yield (18, 62, 5086)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 2091 680866 928091 856918 092160 443597 179051 864558 713318 519197 714264 187602 062308 094406 051954 817436 > 32⁶² [i]
