Linear OA(4208, 217, F4, 143) (dual of [217, 9, 144]-code), using construction X applied to Ce(142) ⊂ Ce(130) based on
- linear OA(4193, 196, F4, 143) (dual of [196, 3, 144]-code), using an extension Ce(142) of the narrow-sense BCH-code C(I) with length 195 | 46−1, defining interval I = [1,142], and designed minimum distance d ≥ |I|+1 = 143 [i]
