Linear OOA(2²⁵², 84, F₂, 4, 102) (dual of [(84, 4), 84, 103]-NRT-code), using strength reduction based on linear OOA(2²⁵², 84, F₂, 4, 104) (dual of [(84, 4), 84, 105]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(64¹⁴, 28, F₆₄, 14) (dual of [28, 14, 15]-code or 28-arc in PG(13,64)), using
  - discarding factors / shortening the dual code based on linear OA(64¹⁴, 64, F₆₄, 14) (dual of [64, 50, 15]-code or 64-arc in PG(13,64)), using
    - Reedâ€“Solomon code RS(50,64) [i]
2. linear OOA(2⁶, 3, F₂, 4, 6) (dual of [(3, 4), 6, 7]-NRT-code), using
