MinT - Best Known (119, 119+133, s)-Nets in Base 4

Best Known (119, 119+133, s)-Nets in Base 4

(119, 119+133, 130)-Net over F₄ — Constructive and digital

Digital (119, 252, 130)-net over F₄, using

t-expansion [i] based on digital (105, 252, 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]

(119, 119+133, 168)-Net over F₄ — Digital

Digital (119, 252, 168)-net over F₄, using

t-expansion [i] based on digital (115, 252, 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]

(119, 119+133, 1596)-Net in Base 4 — Upper bound on s

There is no (119, 252, 1597)-net in base 4, because

1 times m-reduction [i] would yield (119, 251, 1597)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13 255341 479081 160146 043921 427840 218027 531103 902523 236095 570524 472303 741602 059149 978718 677353 143401 422113 485747 706109 751313 253862 191124 120701 829502 665200 > 4²⁵¹ [i]
