Linear OOA(2²⁰³, 52, F₂, 4, 156) (dual of [(52, 4), 5, 157]-NRT-code), using juxtaposition based on

linear OOA(2²³, 7, F₂, 4, 20) (dual of [(7, 4), 5, 21]-NRT-code), using
- extended algebraic-geometric NRT-code AG_e(4;F,7P) [i] based on function field F/F₂ with g(F) = 3 and N(F) ≥ 7, using
  - an explicitly constructive algebraic function field [i]
linear OOA(2¹⁷⁵, 45, F₂, 4, 135) (dual of [(45, 4), 5, 136]-NRT-code), using
- 2¹ times duplication [i] based on linear OOA(2¹⁷⁴, 45, F₂, 4, 135) (dual of [(45, 4), 6, 136]-NRT-code), using
  - concatenation of two NRT-codes [i] based on
    1. linear OA(8⁷, 9, F₈, 7) (dual of [9, 2, 8]-code or 9-arc in PG(6,8)), using
      - extended Reedâ€“Solomon code RS_e(2,8) [i]
      - Simplex code S(2,8) [i]
