(18, 18+74, 51)-Net over F₇ — Digital

Digital (18, 92, 51)-net over F₇, using

net from sequence [i] based on digital (18, 50)-sequence over F₇, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₇ with g(F) = 18 and N(F) ≥ 51, using
  - an algebraic function field by Teo [i]

(18, 18+74, 284)-Net in Base 7 — Upper bound on s

There is no (18, 92, 285)-net in base 7, because

the generalized Rao bound for nets shows that 7^mÂ â‰¥ 574876 563718 326423 792111 869813 472491 489108 635859 915040 718026 528609 698067 951919 > 7⁹² [i]
