Linear OOA(780, 1667, F7, 2, 21) (dual of [(1667, 2), 3254, 22]-NRT-code), using OOA 2-folding based on linear OA(780, 3334, F7, 21) (dual of [3334, 3254, 22]-code), using
- discarding factors / shortening the dual code based on linear OA(780, 3335, F7, 21) (dual of [3335, 3255, 22]-code), using
- 927 step Varšamov–Edel lengthening with (ri) = (2, 4 times 0, 1, 18 times 0, 1, 50 times 0, 1, 108 times 0, 1, 187 times 0, 1, 253 times 0, 1, 300 times 0) [i] based on linear OA(772, 2400, F7, 21) (dual of [2400, 2328, 22]-code), using
- 1 times truncation [i] based on linear OA(773, 2401, F7, 22) (dual of [2401, 2328, 23]-code), using
- an extension Ce(21) of the primitive narrow-sense BCH-code C(I) with length 2400 = 74−1, defining interval I = [1,21], and designed minimum distance d ≥ |I|+1 = 22 [i]
