Linear OA(291, 136, F2, 25) (dual of [136, 45, 26]-code), using construction X applied to C([0,12]) ⊂ C([1,12]) based on
- linear OA(285, 129, F2, 25) (dual of [129, 44, 26]-code), using the expurgated narrow-sense BCH-code C(I) with length 129 | 214−1, defining interval I = [0,12], and minimum distance d ≥ |{−12,−11,…,12}|+1 = 26 (BCH-bound) [i]
- linear OA(284, 129, F2, 18) (dual of [129, 45, 19]-code), using the narrow-sense BCH-code C(I) with length 129 | 214−1, defining interval I = [1,12], and minimum distance d ≥ |{−57,−28,1}| + |{0,64,128,…,56}∖{−1,57}| = 19 (general Roos-bound) [i]
