Best Known (14, 14+20, s)-Nets in Base 4

(14, 14+20, 30)-Net over F₄ — Constructive and digital

Digital (14, 34, 30)-net over F₄, using

t-expansion [i] based on digital (13, 34, 30)-net over F₄, using
- net from sequence [i] based on digital (13, 29)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 13 and N(F) ≥ 30, using
    - F₄ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(14, 14+20, 33)-Net over F₄ — Digital

Digital (14, 34, 33)-net over F₄, using

t-expansion [i] based on digital (13, 34, 33)-net over F₄, using
- net from sequence [i] based on digital (13, 32)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 13 and N(F) ≥ 33, using
    - Drinfeld modules of rank 1 [i]

(14, 14+20, 160)-Net in Base 4 — Upper bound on s

There is no (14, 34, 161)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 303 688744 011498 066928 > 4³⁴ [i]
