Best Known (122, 132, s)-Nets in Base 2

(122, 132, 1677862)-Net over F₂ — Constructive and digital

Digital (122, 132, 1677862)-net over F₂, using

(u,Â u+v)-construction [i] based on
1. digital (12, 17, 142)-net over F₂, using
  - linear code embedding found in a computer search [i]
2. digital (105, 115, 1677720)-net over F₂, using
  - net defined by OOA [i] based on linear OOA(2¹¹⁵, 1677720, F₂, 10, 10) (dual of [(1677720, 10), 16777085, 11]-NRT-code), using
    - OA 5-folding and stacking [i] based on linear OA(2¹¹⁵, 8388600, F₂, 10) (dual of [8388600, 8388485, 11]-code), using
      - discarding factors / shortening the dual code based on linear OA(2¹¹⁵, large, F₂, 10) (dual of [large, large−115, 11]-code), using
        the primitive narrow-sense BCH-code C(I) with length 8388607Â = 2²³âˆ’1, defining interval IÂ =Â [1,10], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 11 [i]

(122, 132, 2796343)-Net over F₂ — Digital

Digital (122, 132, 2796343)-net over F₂, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(2¹³², 2796343, F₂, 3, 10) (dual of [(2796343, 3), 8388897, 11]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(2¹⁷, 142, F₂, 3, 5) (dual of [(142, 3), 409, 6]-NRT-code), using
    - extracting embedded OOA [i] based on digital (12, 17, 142)-net over F₂, using
      - linear code embedding found in a computer search [i]
  2. linear OOA(2¹¹⁵, 2796201, F₂, 3, 10) (dual of [(2796201, 3), 8388488, 11]-NRT-code), using
    - OOA 3-folding [i] based on linear OA(2¹¹⁵, large, F₂, 10) (dual of [large, large−115, 11]-code), using
      - the primitive narrow-sense BCH-code C(I) with length 8388607Â = 2²³âˆ’1, defining interval IÂ =Â [1,10], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 11 [i]

(122, 132, large)-Net in Base 2 — Upper bound on s

There is no (122, 132, large)-net in base 2, because

8 times m-reduction [i] would yield (122, 124, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
