Best Known (49, 156, s)-Nets in Base 8

(49, 156, 98)-Net over F₈ — Constructive and digital

Digital (49, 156, 98)-net over F₈, using

t-expansion [i] based on digital (37, 156, 98)-net over F₈, using
- net from sequence [i] based on digital (37, 97)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 37 and N(F) ≥ 98, using
    - F₅ from the tower of function fields over F₈ by van der Geer and van der Vlugt [i]

(49, 156, 144)-Net over F₈ — Digital

Digital (49, 156, 144)-net over F₈, using

t-expansion [i] based on digital (45, 156, 144)-net over F₈, using
- net from sequence [i] based on digital (45, 143)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 45 and N(F) ≥ 144, using
    - Drinfeld modules of rank 1 [i]

(49, 156, 1254)-Net in Base 8 — Upper bound on s

There is no (49, 156, 1255)-net in base 8, because

1 times m-reduction [i] would yield (49, 155, 1255)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 97 798408 873147 651029 040174 022893 977687 027335 884621 642575 182040 238934 436184 856797 140179 211248 483879 892884 926289 961380 520643 488894 982865 572584 > 8¹⁵⁵ [i]
