Linear OOA(2²⁶⁰, 70, F₂, 4, 157) (dual of [(70, 4), 20, 158]-NRT-code), using strength reduction based on linear OOA(2²⁶⁰, 70, F₂, 4, 164) (dual of [(70, 4), 20, 165]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(32¹⁰, 14, F₃₂, 10) (dual of [14, 4, 11]-code or 14-arc in PG(9,32)), using
  - discarding factors / shortening the dual code based on linear OA(32¹⁰, 32, F₃₂, 10) (dual of [32, 22, 11]-code or 32-arc in PG(9,32)), using
    - Reedâ€“Solomon code RS(22,32) [i]
2. linear OOA(2¹⁵, 5, F₂, 4, 14) (dual of [(5, 4), 5, 15]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(4;F,5P) [i] based on function field F/F₂ with g(F) = 1 and N(F) ≥ 5, using
    - an explicitly constructive algebraic function field [i]
