Best Known (18, 18+14, s)-Nets in Base 9

(18, 18+14, 232)-Net over F₉ — Constructive and digital

Digital (18, 32, 232)-net over F₉, using

trace code for nets [i] based on digital (2, 16, 116)-net over F₈₁, using
- net from sequence [i] based on digital (2, 115)-sequence over F₈₁, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 2 and N(F) ≥ 116, using
    - a function field by SÃ©mirat [i]

(18, 18+14, 236)-Net over F₉ — Digital

Digital (18, 32, 236)-net over F₉, using

trace code for nets [i] based on digital (2, 16, 118)-net over F₈₁, using
- net from sequence [i] based on digital (2, 117)-sequence over F₈₁, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 2 and N(F) ≥ 118, using
    - sharp bound on the number of rational points on curves with genus 2 [i]

(18, 18+14, 9725)-Net in Base 9 — Upper bound on s

There is no (18, 32, 9726)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3 435184 281124 315489 049000 350929 > 9³² [i]
