- linear OA(933, 49, F9, 21) (dual of [49, 16, 22]-code), using
- discarding factors / shortening the dual code based on linear OA(933, 80, F9, 21) (dual of [80, 47, 22]-code), using
- the primitive expurgated narrow-sense BCH-code C(I) with length 80 = 92−1, defining interval I = [0,20], and designed minimum distance d ≥ |I|+1 = 22 [i]
