Linear OA(4240, 247, F4, 172) (dual of [247, 7, 173]-code), using 20 times truncation based on linear OA(4260, 267, F4, 192) (dual of [267, 7, 193]-code), using
- construction X applied to Ce(254) ⊂ Ce(186) [i] based on
- linear OA(4255, 256, F4, 255) (dual of [256, 1, 256]-code or 256-arc in PG(254,4)), using an extension Ce(254) of the primitive narrow-sense BCH-code C(I) with length 255 = 44−1, defining interval I = [1,254], and designed minimum distance d ≥ |I|+1 = 255 [i]
