Linear OA(497, 277, F4, 31) (dual of [277, 180, 32]-code), using construction X applied to Ce(30) ⊂ Ce(25) based on
  1. linear OA(491, 256, F4, 31) (dual of [256, 165, 32]-code), using an extension Ce(30) of the primitive narrow-sense BCH-code C(I) with length 255 = 44−1, defining interval I = [1,30], and designed minimum distance d ≥ |I|+1 = 31 [i]
  2. linear OA(475, 256, F4, 26) (dual of [256, 181, 27]-code), using an extension Ce(25) of the primitive narrow-sense BCH-code C(I) with length 255 = 44−1, defining interval I = [1,25], and designed minimum distance d ≥ |I|+1 = 26 [i]
