Linear OOA(2²¹⁹, 117, F₂, 2, 100) (dual of [(117, 2), 15, 101]-NRT-code), using juxtaposition based on

linear OOA(2²⁵, 20, F₂, 2, 12) (dual of [(20, 2), 15, 13]-NRT-code), using
- discarding factors / shortening the dual code based on linear OOA(2²⁵, 25, F₂, 2, 12) (dual of [(25, 2), 25, 13]-NRT-code), using
  - extracting embedded OOA [i] based on digital (13, 25, 25)-net over F₂, using
    - a shift-net [i]
linear OOA(2¹⁷⁹, 97, F₂, 2, 87) (dual of [(97, 2), 15, 88]-NRT-code), using
- OOA 2-folding [i] based on linear OA(2¹⁷⁹, 194, F₂, 87) (dual of [194, 15, 88]-code), using
  - discarding factors / shortening the dual code based on linear OA(2¹⁷⁹, 195, F₂, 87) (dual of [195, 16, 88]-code), using
    - concatenation of two codes [i] based on
      1. linear OA(4⁵⁷, 65, F₄, 43) (dual of [65, 8, 44]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 65Â | 4⁶âˆ’1, defining interval IÂ =Â [0,21], and minimum distance dÂ â‰¥ |{−21,−20,…,21}|+1Â =Â 44 (BCH-bound) [i]
      2. linear OA(2¹, 3, F₂, 1) (dual of [3, 2, 2]-code), using
        discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
        parity-check code [i]
