  1. linear OOA(259, 26, F25, 2, 9) (dual of [(26, 2), 43, 10]-NRT-code), using
  2. linear OOA(2554, 7818, F25, 2, 18) (dual of [(7818, 2), 15582, 19]-NRT-code), using
    • OOA 2-folding [i] based on linear OA(2554, 15636, F25, 18) (dual of [15636, 15582, 19]-code), using
      • construction X applied to Ce(17) ⊂ Ce(14) [i] based on
        1. linear OA(2552, 15625, F25, 18) (dual of [15625, 15573, 19]-code), using an extension Ce(17) of the primitive narrow-sense BCH-code C(I) with length 15624 = 253−1, defining interval I = [1,17], and designed minimum distance d ≥ |I|+1 = 18 [i]
