Linear OA(2⁴³, 51, F₂, 22) (dual of [51, 8, 23]-code), using strength reduction 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]

Mode: Constructive and linear.
