(20, 20+47, 177)-Net over F₃₂ — Digital

Digital (20, 67, 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+47, 6330)-Net in Base 32 — Upper bound on s

There is no (20, 67, 6331)-net in base 32, because

1 times m-reduction [i] would yield (20, 66, 6331)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 2193 759120 694319 084522 514832 156284 700112 019303 344700 545020 207668 482147 932848 423899 550774 951412 165704 > 32⁶⁶ [i]
