Information on Result #2200550
Linear OA(481, 85, F4, 62) (dual of [85, 4, 63]-code), using strength reduction based on linear OA(481, 85, F4, 63) (dual of [85, 4, 64]-code), using
- Simplex code S(4,4) [i]
- the expurgated narrow-sense BCH-code C(I) with length 85 | 44−1, defining interval I = [0,56], and minimum distance d ≥ |{−6,−5,…,56}|+1 = 64 (BCH-bound) [i]
Mode: Constructive and linear.
