Linear OA(4156, 164, F4, 79) (dual of [164, 8, 80]-code), using construction X applied to C([0,61]) ⊂ C([1,61]) based on
  1. linear OA(4148, 155, F4, 79) (dual of [155, 7, 80]-code), using the expurgated narrow-sense BCH-code C(I) with length 155 | 410−1, defining interval I = [0,61], and minimum distance d ≥ |{−14,−8,−2,…,−11}|+1 = 80 (BCH-bound) [i]
  2. linear OA(4147, 155, F4, 70) (dual of [155, 8, 71]-code), using the narrow-sense BCH-code C(I) with length 155 | 410−1, defining interval I = [1,61], and minimum distance d ≥ |{−65,2}| + |{0,2,4,…,138}∖{60}| = 71 (general Roos-bound) [i]
