Best Known (38, 76, s)-Nets in Base 2

(38, 76, 25)-Net over F₂ — Constructive and digital

Digital (38, 76, 25)-net over F₂, using

(u,Â u+v)-construction [i] based on
1. digital (8, 27, 11)-net over F₂, using
  - net from sequence [i] based on digital (8, 10)-sequence over F₂, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 8 and N(F) ≥ 11, using
      - an explicitly constructive algebraic function field [i]
  - Niederreiterâ€“Xing sequence (PirÅ¡iÄ‡ implementation) with equidistant coordinate [i]
2. digital (11, 49, 14)-net over F₂, using
  - net from sequence [i] based on digital (11, 13)-sequence over F₂, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 11 and N(F) ≥ 14, using
      - an explicitly constructive algebraic function field [i]

(38, 76, 30)-Net over F₂ — Digital

Digital (38, 76, 30)-net over F₂, using

t-expansion [i] based on digital (36, 76, 30)-net over F₂, using
- net from sequence [i] based on digital (36, 29)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 36 and N(F) ≥ 30, using
    - Drinfeld modules of rank 1 [i]

(38, 76, 86)-Net over F₂ — Upper bound on s (digital)

There is no digital (38, 76, 87)-net over F₂, because

extracting embedded orthogonal array [i] would yield linear OA(2⁷⁶, 87, F₂, 38) (dual of [87, 11, 39]-code), but
- â€œJaâ€ bound on codes from Brouwerâ€™s database [i]

(38, 76, 89)-Net in Base 2 — Upper bound on s

There is no (38, 76, 90)-net in base 2, because

extracting embedded orthogonal array [i] would yield OA(2⁷⁶, 90, S₂, 38), but
- the linear programming bound shows that MÂ â‰¥ 22 091230 406864 200309 669888 / 275 > 2⁷⁶ [i]
