Linear OA(4929, 59, F49, 21) (dual of [59, 30, 22]-code), using construction X applied to C([0,10]) ⊂ C([1,10]) based on
  1. linear OA(4921, 50, F49, 21) (dual of [50, 29, 22]-code or 50-arc in PG(20,49)), using the expurgated narrow-sense BCH-code C(I) with length 50 | 492−1, defining interval I = [0,10], and minimum distance d ≥ |{−10,−9,…,10}|+1 = 22 (BCH-bound) [i]
  2. linear OA(4920, 50, F49, 12) (dual of [50, 30, 13]-code), using the narrow-sense BCH-code C(I) with length 50 | 492−1, defining interval I = [1,10], and minimum distance d ≥ |{1,2,…,9}| + |{−21,−10,1,…,0}∖{−22,17,6,−5,−16,23,12,−21}| = 13 (general Roos-bound) [i]
