        discarding factors / shortening the dual code based on linear OOA(256¹⁹, 2796200, F₂₅₆, 4, 7) (dual of [(2796200, 4), 11184781, 8]-NRT-code), using

        discarding factors / shortening the dual code based on linear OA(256¹⁹, large, F₂₅₆, 7) (dual of [large, large−19, 8]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 256³âˆ’1, defining interval IÂ =Â [0,6], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 8 [i]
