Linear OOA(2¹¹⁵, 62, F₂, 2, 57) (dual of [(62, 2), 9, 58]-NRT-code), using (u,Â u+v)-construction based on

linear OOA(2⁵⁴, 31, F₂, 2, 28) (dual of [(31, 2), 8, 29]-NRT-code), using
- 6 step truncation [i] based on linear OOA(2⁶⁰, 34, F₂, 2, 34) (dual of [(34, 2), 8, 35]-NRT-code), using
  - strength reduction [i] based on linear OOA(2⁶⁰, 34, F₂, 2, 35) (dual of [(34, 2), 8, 36]-NRT-code), using
    - concatenation of two NRT-codes [i] based on
      1. linear OA(4¹³, 17, F₄, 11) (dual of [17, 4, 12]-code), using
        projective code from ovoid in PG(3,Â 4) [i]
      2. linear OOA(2², 2, F₂, 2, 2) (dual of [(2, 2), 2, 3]-NRT-code), using
        Reedâ€“Solomon NRT-code RS(2;2,2) [i]
linear OOA(2⁶¹, 31, F₂, 2, 57) (dual of [(31, 2), 1, 58]-NRT-code), using
- strength reduction [i] based on linear OOA(2⁶¹, 31, F₂, 2, 61) (dual of [(31, 2), 1, 62]-NRT-code), using
