Linear OA(477, 136, F4, 20) (dual of [136, 59, 21]-code), using construction X applied to C([0,13]) ⊂ C([1,13]) based on
  1. linear OA(471, 129, F4, 20) (dual of [129, 58, 21]-code), using the expurgated narrow-sense BCH-code C(I) with length 129 | 47−1, defining interval I = [0,13], and minimum distance d ≥ |{−6,−5,…,13}|+1 = 21 (BCH-bound) [i]
  2. linear OA(470, 129, F4, 13) (dual of [129, 59, 14]-code), using the narrow-sense BCH-code C(I) with length 129 | 47−1, defining interval I = [1,13], and designed minimum distance d ≥ |I|+1 = 14 [i]
