Linear OOA(6480, 274, F64, 3, 42) (dual of [(274, 3), 742, 43]-NRT-code), using OOA 3-folding based on linear OA(6480, 822, F64, 42) (dual of [822, 742, 43]-code), using
- construction X applied to Ce(41) ⊂ Ce(40) [i] based on
- linear OA(6480, 820, F64, 42) (dual of [820, 740, 43]-code), using an extension Ce(41) of the narrow-sense BCH-code C(I) with length 819 | 642−1, defining interval I = [1,41], and designed minimum distance d ≥ |I|+1 = 42 [i]
