Linear OOA(2⁷⁸, 55, F₂, 2, 32) (dual of [(55, 2), 32, 33]-NRT-code), using 1 step truncation based on linear OOA(2⁷⁹, 56, F₂, 2, 33) (dual of [(56, 2), 33, 34]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8¹⁷, 14, F₈, 2, 16) (dual of [(14, 2), 11, 17]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,11P) [i] based on function field F/F₈ with g(F) = 1 and N(F) ≥ 14, using
    - F₂ from the tower of function fields over F₈ by van der Geer and van der Vlugt [i]
2. linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 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]
