Best Known (142, 142+30, s)-Nets in Base 8

(142, 142+30, 17485)-Net over F₈ — Constructive and digital

Digital (142, 172, 17485)-net over F₈, using

(u,Â u+v)-construction [i] based on
1. digital (0, 15, 9)-net over F₈, using
  - net from sequence [i] based on digital (0, 8)-sequence over F₈, using
    - generalized Faure sequence [i]
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 0 and N(F) ≥ 9, using
      - the rational function field F₈(x) [i]
    - Niederreiter sequence [i]
2. digital (127, 157, 17476)-net over F₈, using
  - net defined by OOA [i] based on linear OOA(8¹⁵⁷, 17476, F₈, 30, 30) (dual of [(17476, 30), 524123, 31]-NRT-code), using
    - OA 15-folding and stacking [i] based on linear OA(8¹⁵⁷, 262140, F₈, 30) (dual of [262140, 261983, 31]-code), using
      - discarding factors / shortening the dual code based on linear OA(8¹⁵⁷, 262144, F₈, 30) (dual of [262144, 261987, 31]-code), using
        an extension C_e(29) of the primitive narrow-sense BCH-code C(I) with length 262143Â = 8⁶âˆ’1, defining interval IÂ =Â [1,29], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 30 [i]

(142, 142+30, 378703)-Net over F₈ — Digital

Digital (142, 172, 378703)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(142, 142+30, large)-Net in Base 8 — Upper bound on s

There is no (142, 172, large)-net in base 8, because

28 times m-reduction [i] would yield (142, 144, large)-net in base 8, but
- mutually orthogonal hypercube bound [i]
