Linear OA(571, 138, F5, 32) (dual of [138, 67, 33]-code), using construction X applied to Ce(31) ⊂ Ce(23) based on
  1. linear OA(562, 125, F5, 32) (dual of [125, 63, 33]-code), using an extension Ce(31) of the primitive narrow-sense BCH-code C(I) with length 124 = 53−1, defining interval I = [1,31], and designed minimum distance d ≥ |I|+1 = 32 [i]
  2. linear OA(558, 125, F5, 24) (dual of [125, 67, 25]-code), using an extension Ce(23) of the primitive narrow-sense BCH-code C(I) with length 124 = 53−1, defining interval I = [1,23], and designed minimum distance d ≥ |I|+1 = 24 [i]
  3. linear OA(59, 13, F5, 7) (dual of [13, 4, 8]-code), using
