Linear OOA(2²⁰⁸, 54, F₂, 4, 150) (dual of [(54, 4), 8, 151]-NRT-code), using 24 step truncation based on linear OOA(2²³², 60, F₂, 4, 174) (dual of [(60, 4), 8, 175]-NRT-code), using

strength reduction [i] based on linear OOA(2²³², 60, F₂, 4, 175) (dual of [(60, 4), 8, 176]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(16¹⁰, 12, F₁₆, 10) (dual of [12, 2, 11]-code or 12-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]
