Information on Result #2247335

Linear OA(7²⁴, 27, F₇, 20) (dual of [27, 3, 21]-code), using 9 times truncation based on linear OA(7³³, 36, F₇, 29) (dual of [36, 3, 30]-code), using

generalized (u,Â u+v)-construction [i] based on
1. linear OA(7⁴, 6, F₇, 4) (dual of [6, 2, 5]-code or 6-arc in PG(3,7)), using
  - discarding factors / shortening the dual code based on linear OA(7⁴, 7, F₇, 4) (dual of [7, 3, 5]-code or 7-arc in PG(3,7)), using
    - Reedâ€“Solomon code RS(3,7) [i]
2. linear OA(7⁵, 6, F₇, 5) (dual of [6, 1, 6]-code or 6-arc in PG(4,7)), using
  - dual of repetition code with length 6 [i]
3. linear OA(7⁶, 6, F₇, 6) (dual of [6, 0, 7]-code or 6-arc in PG(5,7)), using
  - complete OA / dual of code with only one code word [i]
4. linear OA(7⁶, 6, F₇, 6) (dual of [6, 0, 7]-code or 6-arc in PG(5,7)) (see above)
5. linear OA(7⁶, 6, F₇, 6) (dual of [6, 0, 7]-code or 6-arc in PG(5,7)) (see above)
6. linear OA(7⁶, 6, F₇, 6) (dual of [6, 0, 7]-code or 6-arc in PG(5,7)) (see above)
