Best Known (115, 115+145, s)-Nets in Base 4

(115, 115+145, 130)-Net over F₄ — Constructive and digital

Digital (115, 260, 130)-net over F₄, using

t-expansion [i] based on digital (105, 260, 130)-net over F₄, using
- net from sequence [i] based on digital (105, 129)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 105 and N(F) ≥ 130, using
    - T₇ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(115, 115+145, 168)-Net over F₄ — Digital

Digital (115, 260, 168)-net over F₄, using

net from sequence [i] based on digital (115, 167)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 115 and N(F) ≥ 168, using
  - Drinfeld modules of rank 1 [i]

(115, 115+145, 1290)-Net in Base 4 — Upper bound on s

There is no (115, 260, 1291)-net in base 4, because

1 times m-reduction [i] would yield (115, 259, 1291)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 868319 934755 014474 435867 683083 803927 419830 129261 477651 203420 442194 112770 869636 288900 918442 671600 725459 639621 821716 132892 995979 487797 208290 232993 673927 152380 > 4²⁵⁹ [i]
