Best Known (87, 87+9, s)-Nets in Base 3

(87, 87+9, 2097164)-Net over F₃ — Constructive and digital

Digital (87, 96, 2097164)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (2, 6, 14)-net over F₃, using
  - linear code embedding found in a computer search [i]
2. digital (81, 90, 2097150)-net over F₃, using
  - net defined by OOA [i] based on linear OOA(3⁹⁰, 2097150, F₃, 9, 9) (dual of [(2097150, 9), 18874260, 10]-NRT-code), using
    - OOA 4-folding and stacking with additional row [i] based on linear OA(3⁹⁰, 8388601, F₃, 9) (dual of [8388601, 8388511, 10]-code), using
      - discarding factors / shortening the dual code based on linear OA(3⁹⁰, large, F₃, 9) (dual of [large, large−90, 10]-code), using
        the primitive narrow-sense BCH-code C(I) with length 14348906Â = 3¹⁵âˆ’1, defining interval IÂ =Â [1,9], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 10 [i]

(87, 87+9, 5047835)-Net over F₃ — Digital

Digital (87, 96, 5047835)-net over F₃, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(3⁹⁶, 5047835, F₃, 9) (dual of [5047835, 5047739, 10]-code), using
- discarding factors / shortening the dual code based on linear OA(3⁹⁶, large, F₃, 9) (dual of [large, large−96, 10]-code), using
  - 6 times code embedding in larger space [i] based on linear OA(3⁹⁰, large, F₃, 9) (dual of [large, large−90, 10]-code), using
    - the primitive narrow-sense BCH-code C(I) with length 14348906Â = 3¹⁵âˆ’1, defining interval IÂ =Â [1,9], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 10 [i]

(87, 87+9, large)-Net in Base 3 — Upper bound on s

There is no (87, 96, large)-net in base 3, because

7 times m-reduction [i] would yield (87, 89, large)-net in base 3, but
- mutually orthogonal hypercube bound [i]
