Linear OOA(2²²⁹, 144, F₂, 2, 87) (dual of [(144, 2), 59, 88]-NRT-code), using 1 step truncation based on linear OOA(2²³⁰, 145, F₂, 2, 88) (dual of [(145, 2), 60, 89]-NRT-code), using

strength reduction [i] based on linear OOA(2²³⁰, 145, F₂, 2, 89) (dual of [(145, 2), 60, 90]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(32¹⁷, 29, F₃₂, 17) (dual of [29, 12, 18]-code or 29-arc in PG(16,32)), using
    - discarding factors / shortening the dual code based on linear OA(32¹⁷, 32, F₃₂, 17) (dual of [32, 15, 18]-code or 32-arc in PG(16,32)), using
      - Reedâ€“Solomon code RS(15,32) [i]
  2. linear OOA(2⁵, 5, F₂, 2, 4) (dual of [(5, 2), 5, 5]-NRT-code), using
