Best Known (78, 78+11, s)-Nets in Base 5

(78, 78+11, 1677753)-Net over F₅ — Constructive and digital

Digital (78, 89, 1677753)-net over F₅, using

(u,Â u+v)-construction [i] based on
1. digital (3, 8, 33)-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]

(78, 78+11, 7080509)-Net over F₅ — Digital

Digital (78, 89, 7080509)-net over F₅, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(5⁸⁹, 7080509, F₅, 11) (dual of [7080509, 7080420, 12]-code), using
- discarding factors / shortening the dual code based on linear OA(5⁸⁹, large, F₅, 11) (dual of [large, large−89, 12]-code), using
  - 8 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]

(78, 78+11, large)-Net in Base 5 — Upper bound on s

There is no (78, 89, large)-net in base 5, because

9 times m-reduction [i] would yield (78, 80, large)-net in base 5, but
- mutually orthogonal hypercube bound [i]
