Information on Result #691290

Linear OA(9109, 122, F9, 74) (dual of [122, 13, 75]-code), using construction X applied to Ce(79) ⊂ Ce(51) based on
  1. linear OA(980, 81, F9, 80) (dual of [81, 1, 81]-code or 81-arc in PG(79,9)), using an extension Ce(79) of the primitive narrow-sense BCH-code C(I) with length 80 = 92−1, defining interval I = [1,79], and designed minimum distance d ≥ |I|+1 = 80 [i]
  2. linear OA(968, 81, F9, 52) (dual of [81, 13, 53]-code), using an extension Ce(51) of the primitive narrow-sense BCH-code C(I) with length 80 = 92−1, defining interval I = [1,51], and designed minimum distance d ≥ |I|+1 = 52 [i]
  3. linear OA(929, 41, F9, 21) (dual of [41, 12, 22]-code), using
    • the expurgated narrow-sense BCH-code C(I) with length 41 | 94−1, defining interval I = [0,10], and minimum distance d ≥ |{−10,−9,…,10}|+1 = 22 (BCH-bound) [i]
