- linear OA(840, 52, F8, 28) (dual of [52, 12, 29]-code), using
- discarding factors / shortening the dual code based on linear OA(840, 63, F8, 28) (dual of [63, 23, 29]-code), using
- the primitive expurgated narrow-sense BCH-code C(I) with length 63 = 82−1, defining interval I = [0,27], and designed minimum distance d ≥ |I|+1 = 29 [i]
