Information on Result #1838776
OOA(12877, 2097279, S128, 4, 20), using (u, u+v)-construction based on
- linear OOA(12810, 129, F128, 4, 10) (dual of [(129, 4), 506, 11]-NRT-code), using
- extended Reed–Solomon NRT-code RSe(4;506,128) [i]
- OOA(12867, 2097150, S128, 4, 20), using
- OOA 4-folding [i] based on OA(12867, 8388600, S128, 20), using
- discarding factors based on OA(12867, large, S128, 20), using
- discarding parts of the base [i] based on linear OA(25658, large, F256, 20) (dual of [large, large−58, 21]-code), using
- the primitive expurgated narrow-sense BCH-code C(I) with length 16777215 = 2563−1, defining interval I = [0,19], and designed minimum distance d ≥ |I|+1 = 21 [i]
