Digital (217, 257, 56942)-net over F4, using embedding of OOA with Gilbert–Varšamov bound based on linear OA(4257, 56942, F4, 40) (dual of [56942, 56685, 41]-code), using
- discarding factors / shortening the dual code based on linear OA(4257, 65601, F4, 40) (dual of [65601, 65344, 41]-code), using
- strength reduction [i] based on linear OA(4257, 65601, F4, 41) (dual of [65601, 65344, 42]-code), using
- construction X applied to C([0,20]) ⊂ C([0,16]) [i] based on
- linear OA(4241, 65537, F4, 41) (dual of [65537, 65296, 42]-code), using the expurgated narrow-sense BCH-code C(I) with length 65537 | 416−1, defining interval I = [0,20], and minimum distance d ≥ |{−20,−19,…,20}|+1 = 42 (BCH-bound) [i]
