Linear OA(4246, 1030, F4, 69) (dual of [1030, 784, 70]-code), using construction X applied to Ce(68) ⊂ Ce(62) based on
- linear OA(4241, 1024, F4, 69) (dual of [1024, 783, 70]-code), using an extension Ce(68) of the primitive narrow-sense BCH-code C(I) with length 1023 = 45−1, defining interval I = [1,68], and designed minimum distance d ≥ |I|+1 = 69 [i]
