Linear OA(12863, 150, F128, 43) (dual of [150, 87, 44]-code), using construction X applied to C([0,21]) ⊂ C([1,21]) based on
- linear OA(12843, 129, F128, 43) (dual of [129, 86, 44]-code or 129-arc in PG(42,128)), using the expurgated narrow-sense BCH-code C(I) with length 129 | 1282−1, defining interval I = [0,21], and minimum distance d ≥ |{−21,−20,…,21}|+1 = 44 (BCH-bound) [i]
