Linear OOA(2¹⁴⁰, 80, F₂, 2, 69) (dual of [(80, 2), 20, 70]-NRT-code), using strength reduction based on linear OOA(2¹⁴⁰, 80, F₂, 2, 71) (dual of [(80, 2), 20, 72]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(16¹¹, 16, F₁₆, 11) (dual of [16, 5, 12]-code or 16-arc in PG(10,16)), using
  - Reedâ€“Solomon code RS(5,16) [i]
2. linear OOA(2⁶, 5, F₂, 2, 5) (dual of [(5, 2), 4, 6]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,4P) [i] based on function field F/F₂ with g(F) = 1 and N(F) ≥ 5, using
    - an explicitly constructive algebraic function field [i]
