Linear OOA(2²⁶⁰, 68, F₂, 4, 175) (dual of [(68, 4), 12, 176]-NRT-code), using strength reduction based on linear OOA(2²⁶⁰, 68, F₂, 4, 179) (dual of [(68, 4), 12, 180]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(16¹⁴, 17, F₁₆, 14) (dual of [17, 3, 15]-code or 17-arc in PG(13,16)), using
  - extended Reedâ€“Solomon code RS_e(3,16) [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]
