Linear OA(8127, 91, F81, 19) (dual of [91, 64, 20]-code), using construction X applied to C([0,9]) ⊂ C([1,9]) based on
  1. linear OA(8119, 82, F81, 19) (dual of [82, 63, 20]-code or 82-arc in PG(18,81)), using the expurgated narrow-sense BCH-code C(I) with length 82 | 812−1, defining interval I = [0,9], and minimum distance d ≥ |{−9,−8,…,9}|+1 = 20 (BCH-bound) [i]
  2. linear OA(8118, 82, F81, 10) (dual of [82, 64, 11]-code), using the narrow-sense BCH-code C(I) with length 82 | 812−1, defining interval I = [1,9], and minimum distance d ≥ |{1,2,…,9}| + |{0,9,18,…,81}∖{9,18,27,36,−37,−28,−19,−1}| = 11 (general Roos-bound) [i]
