(60, 60+9, 4194301)-Net over F₉ — Constructive and digital

Digital (60, 69, 4194301)-net over F₉, using

9¹ times duplication [i] based on digital (59, 68, 4194301)-net over F₉, using
- net defined by OOA [i] based on linear OOA(9⁶⁸, 4194301, F₉, 10, 9) (dual of [(4194301, 10), 41942942, 10]-NRT-code), using
  - OOA 2-folding and stacking with additional row [i] based on linear OOA(9⁶⁸, large, F₉, 2, 9), using
    - 1 times NRT-code embedding in larger space [i] based on linear OOA(9⁶⁶, 8388602, F₉, 2, 9) (dual of [(8388602, 2), 16777138, 10]-NRT-code), using
      - trace code [i] based on linear OOA(81³³, 4194301, F₈₁, 2, 9) (dual of [(4194301, 2), 8388569, 10]-NRT-code), using
        OOA 2-folding [i] based on linear OA(81³³, 8388602, F₈₁, 9) (dual of [8388602, 8388569, 10]-code), using
        discarding factors / shortening the dual code based on linear OA(81³³, large, F₈₁, 9) (dual of [large, large−33, 10]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 21523361Â | 81⁸âˆ’1, defining interval IÂ =Â [0,4], and minimum distance dÂ â‰¥ |{−4,−3,…,4}|+1Â =Â 10 (BCH-bound) [i]

(60, 60+9, large)-Net over F₉ — Digital

Digital (60, 69, large)-net over F₉, using

9⁴ times duplication [i] based on digital (56, 65, large)-net over F₉, using
- t-expansion [i] based on digital (55, 65, large)-net over F₉, using
  - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(9⁶⁵, large, F₉, 10) (dual of [large, large−65, 11]-code), using
    - the expurgated narrow-sense BCH-code C(I) with length 21523360Â | 9⁸âˆ’1, defining interval IÂ =Â [0,9], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 11 [i]

(60, 60+9, large)-Net in Base 9 — Upper bound on s

There is no (60, 69, large)-net in base 9, because

7 times m-reduction [i] would yield (60, 62, large)-net in base 9, but
- mutually orthogonal hypercube bound [i]
