Linear OOA(2²⁵⁵, 75, F₂, 4, 131) (dual of [(75, 4), 45, 132]-NRT-code), using strength reduction based on linear OOA(2²⁵⁵, 75, F₂, 4, 135) (dual of [(75, 4), 45, 136]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(32¹⁶, 25, F₃₂, 16) (dual of [25, 9, 17]-code or 25-arc in PG(15,32)), using
  - discarding factors / shortening the dual code based on linear OA(32¹⁶, 32, F₃₂, 16) (dual of [32, 16, 17]-code or 32-arc in PG(15,32)), using
    - Reedâ€“Solomon code RS(16,32) [i]
