Best Known (41, 41+6, s)-Nets in Base 8

(41, 41+6, 5592610)-Net over F₈ — Constructive and digital

Digital (41, 47, 5592610)-net over F₈, using

(u,Â u+v)-construction [i] based on
1. digital (2, 5, 208)-net over F₈, using
  - net defined by OOA [i] based on linear OOA(8⁵, 208, F₈, 3, 3) (dual of [(208, 3), 619, 4]-NRT-code), using
    - appending kth column [i] based on linear OOA(8⁵, 208, F₈, 2, 3) (dual of [(208, 2), 411, 4]-NRT-code), using
      - OAs with strength 3, bÂ â‰ Â 2, and mÂ >Â 3 are always embeddable [i] based on linear OA(8⁵, 208, F₈, 3) (dual of [208, 203, 4]-code or 208-cap in PG(4,8)), using
        caps completed using a computer search [i]
2. digital (36, 42, 5592402)-net over F₈, using
  - trace code for nets [i] based on digital (15, 21, 2796201)-net over F₆₄, using
    - net defined by OOA [i] based on linear OOA(64²¹, 2796201, F₆₄, 6, 6) (dual of [(2796201, 6), 16777185, 7]-NRT-code), using
      - OA 3-folding and stacking [i] based on linear OA(64²¹, large, F₆₄, 6) (dual of [large, large−21, 7]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 64⁴âˆ’1, defining interval IÂ =Â [0,5], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 7 [i]

(41, 41+6, large)-Net over F₈ — Digital

Digital (41, 47, large)-net over F₈, using

8⁶ times duplication [i] based on digital (35, 41, large)-net over F₈, using
- Gilbertâ€“VarÅ¡amov bound [i]

(41, 41+6, large)-Net in Base 8 — Upper bound on s

There is no (41, 47, large)-net in base 8, because

4 times m-reduction [i] would yield (41, 43, large)-net in base 8, but
- mutually orthogonal hypercube bound [i]
