Linear OOA(2²⁴⁸, 65, F₂, 4, 171) (dual of [(65, 4), 12, 172]-NRT-code), using strength reduction based on linear OOA(2²⁴⁸, 65, F₂, 4, 175) (dual of [(65, 4), 12, 176]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(16¹⁰, 13, F₁₆, 10) (dual of [13, 3, 11]-code or 13-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]
2. linear OOA(2¹⁶, 5, F₂, 4, 15) (dual of [(5, 4), 4, 16]-NRT-code), using
