OOA(12869, 2097279, S128, 4, 18), using (u, u+v)-construction based on
- linear OOA(1289, 129, F128, 4, 9) (dual of [(129, 4), 507, 10]-NRT-code), using
- extended Reed–Solomon NRT-code RSe(4;507,128) [i]
- OOA(12860, 2097150, S128, 4, 18), using
- OOA 4-folding [i] based on OA(12860, 8388600, S128, 18), using
- discarding factors based on OA(12860, large, S128, 18), using
- discarding parts of the base [i] based on linear OA(25652, large, F256, 18) (dual of [large, large−52, 19]-code), using
- the primitive expurgated narrow-sense BCH-code C(I) with length 16777215 = 2563−1, defining interval I = [0,17], and designed minimum distance d ≥ |I|+1 = 19 [i]
