(20, 20+57, 177)-Net over F₃₂ — Digital

Digital (20, 77, 177)-net over F₃₂, using

net from sequence [i] based on digital (20, 176)-sequence over F₃₂, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃₂ with g(F) = 20 and N(F) ≥ 177, using

(20, 20+57, 4422)-Net in Base 32 — Upper bound on s

There is no (20, 77, 4423)-net in base 32, because

1 times m-reduction [i] would yield (20, 76, 4423)-net in base 32, but
