Linear OA(4921, 57, F49, 15) (dual of [57, 36, 16]-code), using construction X applied to C([0,7]) ⊂ C([1,7]) based on
  1. linear OA(4915, 50, F49, 15) (dual of [50, 35, 16]-code or 50-arc in PG(14,49)), using the expurgated narrow-sense BCH-code C(I) with length 50 | 492−1, defining interval I = [0,7], and minimum distance d ≥ |{−7,−6,…,7}|+1 = 16 (BCH-bound) [i]
  2. linear OA(4914, 50, F49, 8) (dual of [50, 36, 9]-code), using the narrow-sense BCH-code C(I) with length 50 | 492−1, defining interval I = [1,7], and minimum distance d ≥ |{1,2,…,7}| + |{0,7,14,…,49}∖{7,14,21,−22,−15,−1}| = 9 (general Roos-bound) [i]
