Linear OOA(290, 46, F2, 3, 31) (dual of [(46, 3), 48, 32]-NRT-code), using OOA 3-folding based on linear OA(290, 138, F2, 31) (dual of [138, 48, 32]-code), using
- discarding factors / shortening the dual code based on linear OA(290, 139, F2, 31) (dual of [139, 49, 32]-code), using
- construction X applied to C([0,28]) ⊂ C([0,26]) [i] based on
- linear OA(285, 127, F2, 31) (dual of [127, 42, 32]-code), using the expurgated primitive narrow-sense BCH-code C(I) with length 127 = 27−1, defining interval I = [1,28], and minimum distance d ≥ 32 (sporadic result) and all weights a multiple of 2 because the code is contained in its dual [i]
- linear OA(278, 127, F2, 27) (dual of [127, 49, 28]-code), using the primitive expurgated narrow-sense BCH-code C(I) with length 127 = 27−1, defining interval I = [0,26], and designed minimum distance d ≥ |I|+1 = 28 [i]
