Best Known (17, 49, s)-Nets in Base 4

(17, 49, 33)-Net over F₄ — Constructive and digital

Digital (17, 49, 33)-net over F₄, using

t-expansion [i] based on digital (15, 49, 33)-net over F₄, using
- net from sequence [i] based on digital (15, 32)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 15 and N(F) ≥ 33, using
    - an explicitly constructive algebraic function field [i]

(17, 49, 40)-Net over F₄ — Digital

Digital (17, 49, 40)-net over F₄, using

net from sequence [i] based on digital (17, 39)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 17 and N(F) ≥ 40, using
  - Drinfeld modules of rank 1 [i]

(17, 49, 145)-Net in Base 4 — Upper bound on s

There is no (17, 49, 146)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 324624 589246 685503 165245 503209 > 4⁴⁹ [i]
