Linear OOA(869, 2050, F8, 2, 20) (dual of [(2050, 2), 4031, 21]-NRT-code), using OOA 2-folding based on linear OA(869, 4100, F8, 20) (dual of [4100, 4031, 21]-code), using
- construction X applied to Ce(19) ⊂ Ce(18) [i] based on
- linear OA(869, 4096, F8, 20) (dual of [4096, 4027, 21]-code), using an extension Ce(19) of the primitive narrow-sense BCH-code C(I) with length 4095 = 84−1, defining interval I = [1,19], and designed minimum distance d ≥ |I|+1 = 20 [i]
