Linear OA(2⁴¹, 53, F₂, 18) (dual of [53, 12, 19]-code), using 1 times truncation based on linear OA(2⁴², 54, F₂, 19) (dual of [54, 12, 20]-code), using

concatenation of two codes [i] based on
1. linear OA(4¹², 18, F₄, 9) (dual of [18, 6, 10]-code), using
  - a quaternary quasi-twisted code of dimension 6 by Gulliver and Ã–stergÃ¥rd [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.
