OOA(12873, 2097300, S128, 4, 19), using (u, u+v)-construction based on
- linear OOA(12810, 150, F128, 4, 9) (dual of [(150, 4), 590, 10]-NRT-code), using
- extended algebraic-geometric NRT-code AGe(4;F,590P) [i] based on function field F/F128 with g(F) = 1 and N(F) ≥ 150, using
- OOA(12863, 2097150, S128, 4, 19), using
- OOA 4-folding [i] based on OA(12863, 8388600, S128, 19), using
- discarding factors based on OA(12863, large, S128, 19), using
- discarding parts of the base [i] based on linear OA(25655, large, F256, 19) (dual of [large, large−55, 20]-code), using
- the primitive expurgated narrow-sense BCH-code C(I) with length 16777215 = 2563−1, defining interval I = [0,18], and designed minimum distance d ≥ |I|+1 = 20 [i]
