Linear OA(5¹²⁷, 148, F₅, 77) (dual of [148, 21, 78]-code), using constructionÂ X with VarÅ¡amov bound based on

linear OA(5¹²⁴, 144, F₅, 77) (dual of [144, 20, 78]-code), using
- concatenation of two codes [i] based on
  1. linear OA(25²⁶, 36, F₂₅, 25) (dual of [36, 10, 26]-code), using
    - extended algebraic-geometric code AG_e(F,10P) [i] based on function field F/F₂₅ with g(F) = 1 and N(F) ≥ 36, using
      - sharp bound on the number of rational points on curves with genus 1 [i]
  2. linear OA(5², 4, F₅, 2) (dual of [4, 2, 3]-code or 4-arc in PG(1,5)), using
    - discarding factors / shortening the dual code based on linear OA(5², 5, F₅, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,5)), using
      - Reedâ€“Solomon code RS(3,5) [i]
