Linear OA(7⁷⁷, 91, F₇, 49) (dual of [91, 14, 50]-code), using 1 times truncation based on linear OA(7⁷⁸, 92, F₇, 50) (dual of [92, 14, 51]-code), using

concatenation of two codes [i] based on
1. linear OA(49¹⁶, 23, F₄₉, 16) (dual of [23, 7, 17]-code or 23-arc in PG(15,49)), using
  - discarding factors / shortening the dual code based on linear OA(49¹⁶, 49, F₄₉, 16) (dual of [49, 33, 17]-code or 49-arc in PG(15,49)), using
    - Reedâ€“Solomon code RS(33,49) [i]
2. linear OA(7², 4, F₇, 2) (dual of [4, 2, 3]-code or 4-arc in PG(1,7)), using
  - discarding factors / shortening the dual code based on linear OA(7², 7, F₇, 2) (dual of [7, 5, 3]-code or 7-arc in PG(1,7)), using
    - Reedâ€“Solomon code RS(5,7) [i]
