Linear OOA(2²⁶⁰, 75, F₂, 4, 138) (dual of [(75, 4), 40, 139]-NRT-code), using strength reduction based on linear OOA(2²⁶⁰, 75, F₂, 4, 143) (dual of [(75, 4), 40, 144]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(32¹⁷, 25, F₃₂, 17) (dual of [25, 8, 18]-code or 25-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(2⁷, 3, F₂, 4, 7) (dual of [(3, 4), 5, 8]-NRT-code), using
  - extended Reedâ€“Solomon NRT-code RS_e(4;5,2) [i]
