Best Known (30, 62, s)-Nets in Base 2

(30, 62, 21)-Net over F₂ — Constructive and digital

Digital (30, 62, 21)-net over F₂, using

t-expansion [i] based on digital (21, 62, 21)-net over F₂, using
- net from sequence [i] based on digital (21, 20)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 21 and N(F) ≥ 21, using
    - an explicitly constructive algebraic function field [i]

(30, 62, 25)-Net over F₂ — Digital

Digital (30, 62, 25)-net over F₂, using

t-expansion [i] based on digital (28, 62, 25)-net over F₂, using
- net from sequence [i] based on digital (28, 24)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 28 and N(F) ≥ 25, using
    - a curve from the manYPoints database [i]

(30, 62, 67)-Net over F₂ — Upper bound on s (digital)

There is no digital (30, 62, 68)-net over F₂, because

extracting embedded orthogonal array [i] would yield linear OA(2⁶², 68, F₂, 32) (dual of [68, 6, 33]-code), but
- Griesmer bound [i]

(30, 62, 71)-Net in Base 2 — Upper bound on s

There is no (30, 62, 72)-net in base 2, because

extracting embedded orthogonal array [i] would yield OA(2⁶², 72, S₂, 32), but
- the linear programming bound shows that MÂ â‰¥ 8706 863202 790908 362752 / 1309 > 2⁶² [i]
