Best Known (137, 137+97, s)-Nets in Base 4

(137, 137+97, 137)-Net over F₄ — Constructive and digital

Digital (137, 234, 137)-net over F₄, using

1 times m-reduction [i] based on digital (137, 235, 137)-net over F₄, using
- (u,Â u+v)-construction [i] based on
  1. digital (15, 64, 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]
  2. digital (73, 171, 104)-net over F₄, using
    - net from sequence [i] based on digital (73, 103)-sequence over F₄, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 73 and N(F) ≥ 104, using
        F₆ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(137, 137+97, 300)-Net over F₄ — Digital

Digital (137, 234, 300)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(137, 137+97, 5186)-Net in Base 4 — Upper bound on s

There is no (137, 234, 5187)-net in base 4, because

1 times m-reduction [i] would yield (137, 233, 5187)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 191 242006 419847 693207 846216 099337 070900 267946 481733 822568 006457 853156 144284 122707 335958 735663 055302 578975 970164 301094 875678 038259 552812 139580 > 4²³³ [i]
