Linear OOA(2²⁰⁸, 56, F₂, 4, 130) (dual of [(56, 4), 16, 131]-NRT-code), using strength reduction based on linear OOA(2²⁰⁸, 56, F₂, 4, 131) (dual of [(56, 4), 16, 132]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(16¹⁰, 14, F₁₆, 10) (dual of [14, 4, 11]-code or 14-arc in PG(9,16)), using
  - discarding factors / shortening the dual code based on linear OA(16¹⁰, 16, F₁₆, 10) (dual of [16, 6, 11]-code or 16-arc in PG(9,16)), using
    - Reedâ€“Solomon code RS(6,16) [i]
2. linear OOA(2¹², 4, F₂, 4, 11) (dual of [(4, 4), 4, 12]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(2¹², 5, F₂, 4, 11) (dual of [(5, 4), 8, 12]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(4;F,8P) [i] based on function field F/F₂ with g(F) = 1 and N(F) ≥ 5, using
      - an explicitly constructive algebraic function field [i]
