(68−49, 68, 129)-Net over F₁₆ — Digital

Digital (19, 68, 129)-net over F₁₆, using

net from sequence [i] based on digital (19, 128)-sequence over F₁₆, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 19 and N(F) ≥ 129, using

(68−49, 68, 1489)-Net in Base 16 — Upper bound on s

There is no (19, 68, 1490)-net in base 16, because

1 times m-reduction [i] would yield (19, 67, 1490)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 479 725671 102251 812719 276685 352429 901166 338585 469659 682617 096694 482200 280272 882776 > 16⁶⁷ [i]
