Information on Result #670362

Linear OA(8178, 531770, F81, 21) (dual of [531770, 531692, 22]-code), using (u, u+v)-construction based on
  1. linear OA(8117, 328, F81, 10) (dual of [328, 311, 11]-code), using
    • the BCH-code C(I) with length 328 | 812−1, defining interval I = {81,114,147,…,50}, and designed minimum distance d ≥ |I|+1 = 11 [i]
  2. linear OA(8161, 531442, F81, 21) (dual of [531442, 531381, 22]-code), using
    • the expurgated narrow-sense BCH-code C(I) with length 531442 | 816−1, defining interval I = [0,10], and minimum distance d ≥ |{−10,−9,…,10}|+1 = 22 (BCH-bound) [i]
