Linear OA(5¹²⁰, 140, F₅, 71) (dual of [140, 20, 72]-code), using concatenation of two codes based on

linear OA(25¹⁸, 28, F₂₅, 17) (dual of [28, 10, 18]-code), using
- constructionÂ X applied to RS(8,25) âŠ‚ RS(10,25) [i] based on
  1. linear OA(25¹⁷, 25, F₂₅, 17) (dual of [25, 8, 18]-code or 25-arc in PG(16,25)), using Reedâ€“Solomon code RS(8,25) [i]
  2. linear OA(25¹⁵, 25, F₂₅, 15) (dual of [25, 10, 16]-code or 25-arc in PG(14,25)), using Reedâ€“Solomon code RS(10,25) [i]
  3. linear OA(25¹, 3, F₂₅, 1) (dual of [3, 2, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(25¹, s, F₂₅, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
linear OA(5³, 5, F₅, 3) (dual of [5, 2, 4]-code or 5-arc in PG(2,5) or 5-cap in PG(2,5)), using
