Linear OA(4132, 287, F4, 42) (dual of [287, 155, 43]-code), using construction XX applied to C([0,21]) ⊂ C([0,18]) ⊂ C([0,17]) based on
  1. linear OA(4121, 257, F4, 43) (dual of [257, 136, 44]-code), using the expurgated narrow-sense BCH-code C(I) with length 257 | 48−1, defining interval I = [0,21], and minimum distance d ≥ |{−21,−20,…,21}|+1 = 44 (BCH-bound) [i]
