Linear OOA(6473, 274, F64, 3, 38) (dual of [(274, 3), 749, 39]-NRT-code), using OOA 3-folding based on linear OA(6473, 822, F64, 38) (dual of [822, 749, 39]-code), using
- construction X applied to Ce(37) ⊂ Ce(36) [i] based on
- linear OA(6473, 820, F64, 38) (dual of [820, 747, 39]-code), using an extension Ce(37) of the narrow-sense BCH-code C(I) with length 819 | 642−1, defining interval I = [1,37], and designed minimum distance d ≥ |I|+1 = 38 [i]
