  - linear code embedding found in a computer search [i]
2. digital (189, 207, 932067)-net over F₂, using
  - net defined by OOA [i] based on linear OOA(2²⁰⁷, 932067, F₂, 18, 18) (dual of [(932067, 18), 16776999, 19]-NRT-code), using
    - OA 9-folding and stacking [i] based on linear OA(2²⁰⁷, large, F₂, 18) (dual of [large, large−207, 19]-code), using
      - the primitive narrow-sense BCH-code C(I) with length 8388607Â = 2²³âˆ’1, defining interval IÂ =Â [1,18], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 19 [i]

(208, 226, large)-Net in Base 2 — Upper bound on s

There is no (208, 226, large)-net in base 2, because

16 times m-reduction [i] would yield (208, 210, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
