Linear OOA(2²⁴⁷, 143, F₂, 2, 106) (dual of [(143, 2), 39, 107]-NRT-code), using 3 step truncation based on linear OOA(2²⁵⁰, 145, F₂, 2, 109) (dual of [(145, 2), 40, 110]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(32²¹, 29, F₃₂, 21) (dual of [29, 8, 22]-code or 29-arc in PG(20,32)), using
  - discarding factors / shortening the dual code based on linear OA(32²¹, 32, F₃₂, 21) (dual of [32, 11, 22]-code or 32-arc in PG(20,32)), using
    - Reedâ€“Solomon code RS(11,32) [i]
2. linear OOA(2⁵, 5, F₂, 2, 4) (dual of [(5, 2), 5, 5]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;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]
