(38, 91, 128)-Net over F₉ — Digital

Digital (38, 91, 128)-net over F₉, using

t-expansion [i] based on digital (33, 91, 128)-net over F₉, using
- net from sequence [i] based on digital (33, 127)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 33 and N(F) ≥ 128, using

(38, 91, 2634)-Net in Base 9 — Upper bound on s

There is no (38, 91, 2635)-net in base 9, because

1 times m-reduction [i] would yield (38, 90, 2635)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 76 241299 118859 085107 006406 409645 523970 819581 081443 581156 941411 970624 986300 168943 265649 > 9⁹⁰ [i]
