MinT - Best Known (172−111, 172, s)-Nets in Base 8

Best Known (172−111, 172, s)-Nets in Base 8

(172−111, 172, 98)-Net over F₈ — Constructive and digital

Digital (61, 172, 98)-net over F₈, using

t-expansion [i] based on digital (37, 172, 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]

(172−111, 172, 144)-Net over F₈ — Digital

Digital (61, 172, 144)-net over F₈, using

t-expansion [i] based on digital (45, 172, 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]

(172−111, 172, 1923)-Net in Base 8 — Upper bound on s

There is no (61, 172, 1924)-net in base 8, because

1 times m-reduction [i] would yield (61, 171, 1924)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 27201 123126 181388 427563 840123 762731 985416 060787 992629 837533 600764 807487 597478 106104 767823 298627 224288 637125 139393 641970 346210 905676 482013 328724 017769 670816 > 8¹⁷¹ [i]
