Linear OA(2120, 160, F2, 43) (dual of [160, 40, 44]-code), using adding a parity check bit based on linear OA(2119, 159, F2, 42) (dual of [159, 40, 43]-code), using
- construction X applied to C([1,42]) ⊂ C([1,28]) [i] based on
- linear OA(298, 127, F2, 42) (dual of [127, 29, 43]-code), using the primitive narrow-sense BCH-code C(I) with length 127 = 27−1, defining interval I = [1,42], and designed minimum distance d ≥ |I|+1 = 43 [i]
- linear OA(284, 127, F2, 30) (dual of [127, 43, 31]-code), using the primitive narrow-sense BCH-code C(I) with length 127 = 27−1, defining interval I = [1,28], and minimum distance d ≥ 31 (sporadic result) [i]
- linear OA(221, 32, F2, 11) (dual of [32, 11, 12]-code), using
- an extension Ce(10) of the primitive narrow-sense BCH-code C(I) with length 31 = 25−1, defining interval I = [1,10], and designed minimum distance d ≥ |I|+1 = 11 [i]
