Digital (20, 38, 128)-net over F₇, using

trace code for nets [i] based on digital (1, 19, 64)-net over F₄₉, using
- net from sequence [i] based on digital (1, 63)-sequence over F₄₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄₉ with g(F) = 1 and N(F) ≥ 64, using
    - sharp bound on the number of rational points on curves with genus 1 [i]

(38−18, 38, 2551)-Net in Base 7 — Upper bound on s

There is no (20, 38, 2552)-net in base 7, because

the generalized Rao bound for nets shows that 7^mÂ â‰¥ 129 996850 964854 355893 024701 333841 > 7³⁸ [i]
