Linear OOA(2²⁵⁸, 72, F₂, 4, 148) (dual of [(72, 4), 30, 149]-NRT-code), using strength reduction based on linear OOA(2²⁵⁸, 72, F₂, 4, 151) (dual of [(72, 4), 30, 152]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(32¹⁸, 24, F₃₂, 18) (dual of [24, 6, 19]-code or 24-arc in PG(17,32)), using
  - discarding factors / shortening the dual code based on linear OA(32¹⁸, 32, F₃₂, 18) (dual of [32, 14, 19]-code or 32-arc in PG(17,32)), using
    - Reedâ€“Solomon code RS(14,32) [i]
