Best Known (97−13, 97, s)-Nets in Base 8

(97−13, 97, 1398117)-Net over F₈ — Constructive and digital

Digital (84, 97, 1398117)-net over F₈, using

(u,Â u+v)-construction [i] based on
1. digital (2, 8, 17)-net over F₈, using
  - net from sequence [i] based on digital (2, 16)-sequence over F₈, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 2 and N(F) ≥ 17, using
      - a function field by SÃ©mirat [i]
2. digital (76, 89, 1398100)-net over F₈, using
  - net defined by OOA [i] based on linear OOA(8⁸⁹, 1398100, F₈, 13, 13) (dual of [(1398100, 13), 18175211, 14]-NRT-code), using
    - OOA 6-folding and stacking with additional row [i] based on linear OA(8⁸⁹, 8388601, F₈, 13) (dual of [8388601, 8388512, 14]-code), using
      - discarding factors / shortening the dual code based on linear OA(8⁸⁹, large, F₈, 13) (dual of [large, large−89, 14]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 8⁸âˆ’1, defining interval IÂ =Â [0,12], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 14 [i]

(97−13, 97, large)-Net over F₈ — Digital

Digital (84, 97, large)-net over F₈, using

t-expansion [i] based on digital (83, 97, large)-net over F₈, using
- embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(8⁹⁷, large, F₈, 14) (dual of [large, large−97, 15]-code), using
  - the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 8⁸âˆ’1, defining interval IÂ =Â [0,13], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 15 [i]

(97−13, 97, large)-Net in Base 8 — Upper bound on s

There is no (84, 97, large)-net in base 8, because

11 times m-reduction [i] would yield (84, 86, large)-net in base 8, but
- mutually orthogonal hypercube bound [i]
