Information on Result #2258686
Linear OA(250, 68, F2, 21) (dual of [68, 18, 22]-code), using 4 times code embedding in larger space based on linear OA(246, 64, F2, 21) (dual of [64, 18, 22]-code), using
- an extension Ce(20) of the primitive narrow-sense BCH-code C(I) with length 63 = 26−1, defining interval I = [1,20], and designed minimum distance d ≥ |I|+1 = 21 [i]
