Linear OOA(2²⁵⁷, 78, F₂, 4, 104) (dual of [(78, 4), 55, 105]-NRT-code), using OOA 2-folding based on linear OOA(2²⁵⁷, 156, F₂, 2, 104) (dual of [(156, 2), 55, 105]-NRT-code), using

1 times NRT-code embedding in larger space [i] based on linear OOA(2²⁵⁵, 155, F₂, 2, 104) (dual of [(155, 2), 55, 105]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(32²⁰, 31, F₃₂, 20) (dual of [31, 11, 21]-code or 31-arc in PG(19,32)), using
    - discarding factors / shortening the dual code based on linear OA(32²⁰, 32, F₃₂, 20) (dual of [32, 12, 21]-code or 32-arc in PG(19,32)), using
      - Reedâ€“Solomon code RS(12,32) [i]
  2. linear OOA(2⁵, 5, F₂, 2, 4) (dual of [(5, 2), 5, 5]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,5P) [i] based on function field F/F₂ with g(F) = 1 and N(F) ≥ 5, using
      - an explicitly constructive algebraic function field [i]
