Best Known (93, 93+8, s)-Nets in Base 3

(93, 93+8, 2628590)-Net over F₃ — Constructive and digital

Digital (93, 101, 2628590)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (21, 25, 531440)-net over F₃, using
  - nets constructed from net-embeddable BCH codes [i]
2. digital (68, 76, 2097150)-net over F₃, using
  - net defined by OOA [i] based on linear OOA(3⁷⁶, 2097150, F₃, 8, 8) (dual of [(2097150, 8), 16777124, 9]-NRT-code), using
    - OA 4-folding and stacking [i] based on linear OA(3⁷⁶, 8388600, F₃, 8) (dual of [8388600, 8388524, 9]-code), using
      - discarding factors / shortening the dual code based on linear OA(3⁷⁶, large, F₃, 8) (dual of [large, large−76, 9]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 14348906Â = 3¹⁵âˆ’1, defining interval IÂ =Â [0,7], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 9 [i]

(93, 93+8, large)-Net over F₃ — Digital

Digital (93, 101, large)-net over F₃, using

3¹ times duplication [i] based on digital (92, 100, large)-net over F₃, using
- t-expansion [i] based on digital (91, 100, large)-net over F₃, using
  - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(3¹⁰⁰, large, F₃, 9) (dual of [large, large−100, 10]-code), using
    - 10 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]

(93, 93+8, large)-Net in Base 3 — Upper bound on s

There is no (93, 101, large)-net in base 3, because

6 times m-reduction [i] would yield (93, 95, large)-net in base 3, but
- mutually orthogonal hypercube bound [i]
