Linear OA(4139, 277, F4, 47) (dual of [277, 138, 48]-code), using construction X applied to Ce(46) ⊂ Ce(41) based on
  1. linear OA(4133, 256, F4, 47) (dual of [256, 123, 48]-code), using an extension Ce(46) of the primitive narrow-sense BCH-code C(I) with length 255 = 44−1, defining interval I = [1,46], and designed minimum distance d ≥ |I|+1 = 47 [i]
  2. linear OA(4117, 256, F4, 42) (dual of [256, 139, 43]-code), using an extension Ce(41) of the primitive narrow-sense BCH-code C(I) with length 255 = 44−1, defining interval I = [1,41], and designed minimum distance d ≥ |I|+1 = 42 [i]
