Digital (81, 91, 1677788)-net over F₅, using

t-expansion [i] based on digital (80, 91, 1677788)-net over F₅, using
- (u,Â u+v)-construction [i] based on
  1. digital (5, 10, 68)-net over F₅, using
    - linear code embedding found in a computer search [i]
  2. digital (70, 81, 1677720)-net over F₅, using
    - net defined by OOA [i] based on linear OOA(5⁸¹, 1677720, F₅, 11, 11) (dual of [(1677720, 11), 18454839, 12]-NRT-code), using
      - OOA 5-folding and stacking with additional row [i] based on linear OA(5⁸¹, 8388601, F₅, 11) (dual of [8388601, 8388520, 12]-code), using
        discarding factors / shortening the dual code based on linear OA(5⁸¹, large, F₅, 11) (dual of [large, large−81, 12]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 9765626Â | 5²⁰âˆ’1, defining interval IÂ =Â [0,5], and minimum distance dÂ â‰¥ |{−5,−4,…,5}|+1Â =Â 12 (BCH-bound) [i]

(91−10, 91, large)-Net over F₅ — Digital

Digital (81, 91, large)-net over F₅, using

5¹ times duplication [i] based on digital (80, 90, large)-net over F₅, using
- t-expansion [i] based on digital (79, 90, large)-net over F₅, using
  - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(5⁹⁰, large, F₅, 11) (dual of [large, large−90, 12]-code), using
    - 9 times code embedding in larger space [i] based on linear OA(5⁸¹, large, F₅, 11) (dual of [large, large−81, 12]-code), using
      - the expurgated narrow-sense BCH-code C(I) with length 9765626Â | 5²⁰âˆ’1, defining interval IÂ =Â [0,5], and minimum distance dÂ â‰¥ |{−5,−4,…,5}|+1Â =Â 12 (BCH-bound) [i]

(91−10, 91, large)-Net in Base 5 — Upper bound on s

There is no (81, 91, large)-net in base 5, because

8 times m-reduction [i] would yield (81, 83, large)-net in base 5, but
- mutually orthogonal hypercube bound [i]
