MinT - Best Known (18, 63, s)-Nets in Base 7

Best Known (18, 63, s)-Nets in Base 7

(18, 63, 26)-Net over F₇ — Constructive and digital

Digital (18, 63, 26)-net over F₇, using

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

(18, 63, 51)-Net over F₇ — Digital

Digital (18, 63, 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, 63, 349)-Net in Base 7 — Upper bound on s

There is no (18, 63, 350)-net in base 7, because

1 times m-reduction [i] would yield (18, 62, 350)-net in base 7, but
- the generalized Rao bound for nets shows that 7^mÂ â‰¥ 25855 459531 671031 473392 092451 731166 157623 867591 808181 > 7⁶² [i]
