Best Known (29, 29+184, s)-Nets in Base 4

(29, 29+184, 34)-Net over F₄ — Constructive and digital

Digital (29, 213, 34)-net over F₄, using

t-expansion [i] based on digital (21, 213, 34)-net over F₄, using
- net from sequence [i] based on digital (21, 33)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 21 and N(F) ≥ 34, using
    - T₅ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(29, 29+184, 42)-Net in Base 4 — Constructive

(29, 213, 42)-net in base 4, using

t-expansion [i] based on (27, 213, 42)-net in base 4, using
- net from sequence [i] based on (27, 41)-sequence in base 4, using
  - base expansion [i] based on digital (54, 41)-sequence over F₂, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 54 and N(F) ≥ 42, using
      - an explicitly constructive algebraic function field [i]

(29, 29+184, 55)-Net over F₄ — Digital

Digital (29, 213, 55)-net over F₄, using

t-expansion [i] based on digital (26, 213, 55)-net over F₄, using
- net from sequence [i] based on digital (26, 54)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 26 and N(F) ≥ 55, using
    - Drinfeld modules of rank 1 [i]

(29, 29+184, 104)-Net in Base 4 — Upper bound on s

There is no (29, 213, 105)-net in base 4, because

7 times m-reduction [i] would yield (29, 206, 105)-net in base 4, but
- extracting embedded OOA [i] would yield OOA(4²⁰⁶, 105, S₄, 2, 177), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 1 099997 132066 973668 655987 072566 531010 274465 392452 563948 889655 595336 611236 617222 079453 114846 171686 233986 391776 809638 868218 281984 / 89 > 4²⁰⁶ [i]
