Best Known (18, 18+28, s)-Nets in Base 7

(18, 18+28, 26)-Net over F₇ — Constructive and digital

Digital (18, 46, 26)-net over F₇, using

net from sequence [i] based on digital (18, 25)-sequence over F₇, using
- Niederreiter sequence [i]

(18, 18+28, 51)-Net over F₇ — Digital

Digital (18, 46, 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+28, 593)-Net in Base 7 — Upper bound on s

There is no (18, 46, 594)-net in base 7, because

the generalized Rao bound for nets shows that 7^mÂ â‰¥ 751 694429 279841 037738 553483 778915 769213 > 7⁴⁶ [i]
