Linear OA(2¹⁷¹, 179, F₂, 87) (dual of [179, 8, 88]-code), using adding a parity check bit based on linear OA(2¹⁷⁰, 178, F₂, 86) (dual of [178, 8, 87]-code), using

juxtaposition [i] based on
1. linear OA(2⁴², 50, F₂, 22) (dual of [50, 8, 23]-code), using
  - 1 times truncation [i] based on linear OA(2⁴³, 51, F₂, 23) (dual of [51, 8, 24]-code), using
    - concatenation of two codes [i] based on
      1. linear OA(4¹³, 17, F₄, 11) (dual of [17, 4, 12]-code), using
        projective code from ovoid in PG(3,Â 4) [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]
