Linear OOA(2²³⁸, 64, F₂, 4, 148) (dual of [(64, 4), 18, 149]-NRT-code), using 4 step truncation based on linear OOA(2²⁴², 65, F₂, 4, 152) (dual of [(65, 4), 18, 153]-NRT-code), using

strength reduction [i] based on linear OOA(2²⁴², 65, F₂, 4, 153) (dual of [(65, 4), 18, 154]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(64¹⁰, 13, F₆₄, 10) (dual of [13, 3, 11]-code or 13-arc in PG(9,64)), using
    - discarding factors / shortening the dual code based on linear OA(64¹⁰, 64, F₆₄, 10) (dual of [64, 54, 11]-code or 64-arc in PG(9,64)), using
      - Reedâ€“Solomon code RS(54,64) [i]
  2. linear OOA(2¹⁴, 5, F₂, 4, 13) (dual of [(5, 4), 6, 14]-NRT-code), using
