Linear OA(2216, 228, F2, 81) (dual of [228, 12, 82]-code), using construction X applied to C([0,72]) ⊂ C([1,72]) based on
  1. linear OA(2208, 219, F2, 81) (dual of [219, 11, 82]-code), using the expurgated narrow-sense BCH-code C(I) with length 219 | 218−1, defining interval I = [0,72], and minimum distance d ≥ |{−8,−7,…,72}|+1 = 82 (BCH-bound) [i]
  2. linear OA(2207, 219, F2, 72) (dual of [219, 12, 73]-code), using the narrow-sense BCH-code C(I) with length 219 | 218−1, defining interval I = [1,72], and designed minimum distance d ≥ |I|+1 = 73 [i]
