(20, 20+61, 177)-Net over F₃₂ — Digital

Digital (20, 81, 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+61, 3994)-Net in Base 32 — Upper bound on s

There is no (20, 81, 3995)-net in base 32, because

1 times m-reduction [i] would yield (20, 80, 3995)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 2 588210 028242 436880 115575 973147 050805 534780 472517 342953 236284 965988 084332 849131 322906 631215 114108 979494 587913 258277 845920 > 32⁸⁰ [i]
