Linear OA(4142, 148, F4, 103) (dual of [148, 6, 104]-code), using juxtaposition based on
  1. linear OA(457, 63, F4, 43) (dual of [63, 6, 44]-code), using
    • contraction [i] based on linear OA(4183, 189, F4, 131) (dual of [189, 6, 132]-code), using the expurgated narrow-sense BCH-code C(I) with length 189 | 49−1, defining interval I = [0,128], and minimum distance d ≥ |{−2,−1,…,128}|+1 = 132 (BCH-bound) [i]
  2. linear OA(479, 85, F4, 59) (dual of [85, 6, 60]-code), using
    • the BCH-code C(I) with length 85 | 44−1, defining interval I = {−4,2,8,…,4}, and designed minimum distance d ≥ |I|+1 = 60 [i]
