MinT - Best Known (71−49, 71, s)-Nets in Base 7

Best Known (71−49, 71, s)-Nets in Base 7

(71−49, 71, 29)-Net over F₇ — Constructive and digital

Digital (22, 71, 29)-net over F₇, using

t-expansion [i] based on digital (21, 71, 29)-net over F₇, using
- net from sequence [i] based on digital (21, 28)-sequence over F₇, using
  - Niederreiter sequence [i]

(71−49, 71, 72)-Net over F₇ — Digital

Digital (22, 71, 72)-net over F₇, using

net from sequence [i] based on digital (22, 71)-sequence over F₇, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₇ with g(F) = 22 and N(F) ≥ 72, using
  - an algebraic function field over â„¤₇ by Yeo [i]

(71−49, 71, 461)-Net in Base 7 — Upper bound on s

There is no (22, 71, 462)-net in base 7, because

1 times m-reduction [i] would yield (22, 70, 462)-net in base 7, but
- the generalized Rao bound for nets shows that 7^mÂ â‰¥ 149549 138980 198380 500471 772689 465243 271980 125181 104807 667377 > 7⁷⁰ [i]
