MinT - Best Known (157−109, 157, s)-Nets in Base 8

Best Known (157−109, 157, s)-Nets in Base 8

(157−109, 157, 98)-Net over F₈ — Constructive and digital

Digital (48, 157, 98)-net over F₈, using

t-expansion [i] based on digital (37, 157, 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]

(157−109, 157, 144)-Net over F₈ — Digital

Digital (48, 157, 144)-net over F₈, using

t-expansion [i] based on digital (45, 157, 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]

(157−109, 157, 1183)-Net in Base 8 — Upper bound on s

There is no (48, 157, 1184)-net in base 8, because

1 times m-reduction [i] would yield (48, 156, 1184)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 786 154373 094140 214742 969185 645389 947603 042437 922075 341197 427699 174847 238460 612864 139861 841703 198902 206436 102513 693040 937601 770109 219273 318396 > 8¹⁵⁶ [i]
