Linear OA(7⁸⁵, 107, F₇, 50) (dual of [107, 22, 51]-code), using 1 times truncation based on linear OA(7⁸⁶, 108, F₇, 51) (dual of [108, 22, 52]-code), using

concatenation of two codes [i] based on
1. linear OA(49²⁵, 36, F₄₉, 25) (dual of [36, 11, 26]-code or 36-arc in PG(24,49)), using
  - discarding factors / shortening the dual code based on linear OA(49²⁵, 49, F₄₉, 25) (dual of [49, 24, 26]-code or 49-arc in PG(24,49)), using
    - Reedâ€“Solomon code RS(24,49) [i]
2. linear OA(7¹, 3, F₇, 1) (dual of [3, 2, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(7¹, s, F₇, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
