Linear OA(493, 97, F4, 70) (dual of [97, 4, 71]-code), using juxtaposition based on
- linear OA(48, 12, F4, 6) (dual of [12, 4, 7]-code), using
- discarding factors / shortening the dual code based on linear OA(48, 16, F4, 6) (dual of [16, 8, 7]-code), using
- an extension Ce(5) of the primitive narrow-sense BCH-code C(I) with length 15 = 42−1, defining interval I = [1,5], and designed minimum distance d ≥ |I|+1 = 6 [i]
- discarding factors / shortening the dual code based on linear OA(48, 16, F4, 6) (dual of [16, 8, 7]-code), using
- linear OA(481, 85, F4, 63) (dual of [85, 4, 64]-code), using
- Simplex code S(4,4) [i]
- the expurgated narrow-sense BCH-code C(I) with length 85 | 44−1, defining interval I = [0,56], and minimum distance d ≥ |{−6,−5,…,56}|+1 = 64 (BCH-bound) [i]
