Linear OOA(2²³⁸, 89, F₂, 3, 126) (dual of [(89, 3), 29, 127]-NRT-code), using 2 step truncation based on linear OOA(2²⁴⁰, 90, F₂, 3, 128) (dual of [(90, 3), 30, 129]-NRT-code), using

strength reduction [i] based on linear OOA(2²⁴⁰, 90, F₂, 3, 129) (dual of [(90, 3), 30, 130]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OA(32¹², 18, F₃₂, 12) (dual of [18, 6, 13]-code or 18-arc in PG(11,32)), using
    - discarding factors / shortening the dual code based on linear OA(32¹², 32, F₃₂, 12) (dual of [32, 20, 13]-code or 32-arc in PG(11,32)), using
      - Reedâ€“Solomon code RS(20,32) [i]
  2. linear OOA(2¹⁰, 5, F₂, 3, 9) (dual of [(5, 3), 5, 10]-NRT-code), using
